Joint ICTP/SISSA Statistical Physics seminar: "Finite temperature correlations in the 1D Lieb-Liniger Bose gas"
We address the problem of calculating finite-temperature response functions of an experimentally relevant low-dimensional strongly-correlated system: the integrable 1D Bose gas with repulsive δ-function interaction (Lieb-Liniger model). Focusing on the dynamical density-density function, we present a Bethe Ansatz-based method allowing for its accurate evaluation in finite but large systems, over broad ranges of momenta, frequencies, temperatures and interaction parameters which are difficult to access using other methods. This allows us to quantify the reshaping of the zero temperature critical behavior by thermal fluctuations, in experimentally accessible regimes.

Joint ICTP/SISSA Colloquium on Condensed Matter Physics: "Kinks and failure in isostatic networks"
A minimal model for studying the mechanical properties of amorphous solids is a disordered elastic network of point masses connected by springs. At a critical (isostatic) value of its mean connectivity, such a network undergoes a rigidity transition signaled by vanishing elastic moduli and corresponding sound speed(s). We first investigate analytically and numerically the linear and non-linear visco-elastic response of these nearly isostatic networks by probing how shear fronts propagate through them.
Our approach, that we tentatively label shear front rheology, provides an alternative route to standard oscillatory rheology. In the linear regime, we observe at late times a diffusive broadening of the fronts controlled by an effective shear viscosity that diverges at the critical point. No matter how small the microscopic coefficient of dissipation, strongly disordered networks behave as if they were over-damped because energy is irreversibly leaked into diverging non-affine fluctuations. Close to the transition, the regime of linear response becomes vanishingly small: the tiniest shear strains generate strongly non-linear shear shock waves. The inherent non-linearities trigger an energy cascade from low to high frequency components that keep the network away from attaining the quasi-static limit. This mechanism, reminiscent of acoustic turbulence, causes a super-diffusive broadening of the shock width.
Finally, we show that the mechanism of failure of such networks, consists of meandering cracks whose width diverges at the transition. Thus, upon approaching the critical point, we can effectively zoom inside the fracture process zone.

Joint ICTP/SISSA Statistical Physics seminar: "A functional RG equation for the c-function"
After showing how to prove the integrated c-theorem within the functional RG framework based on the effective average action, we derive an exact RG flow equation for Zamolodchikov's c-function in two dimensions by relating it to the flow of the effective average action. In order to obtain a non-trivial flow for the c-function, we will need to understand the general form of the effective average action away from criticality, where nonlocal invariants, with beta functions as coefficients, must be included in the ansatz to be consistent. We then apply our construction to several examples: exact results, local potential approximation and loop expansion. In each case we construct the relative approximate c-function and find it to be consistent with Zamolodchikov's c-theorem. Finally, we present a relation between the c-function and the (matter induced) beta function of Newton's constant, allowing us to use heat kernel techniques to compute the RG running of the c-function.

Salam Distinguished Lectures 2014: "Theory of Quantum Matter: from Quantum Fields to Strings"
Abstract: The quasiparticle concept is the foundation of our understanding of the dynamics of
many-body quantum systems. It originated in the theory of metals, which have electron-like
quasiparticles; but it is also useful in more exotic states like those found in
fractional quantum Hall systems. However, modern materials abound in systems to which the
quasiparticle picture does not apply, and developing their theoretical description remains one of the
most important challenges in condensed matter physics. I will present an elementary description of
two key models without quasiparticle excitations, both motivated by recent
experiments.
The first is the superfluid-insulator transition of ultracold bosonic atoms trapped in optical lattices in two spatial dimensions. Its low energy theory is a conformal field theory in 2+1 spacetime dimensions, and this fact allows us to gain insight from the AdS/CFT correspondence of string theory.
The second model is the Pomeranchuk instability of two dimensional metals at which 90 degree lattice rotation symmetry is broken. Such an instability has been found to play a prominent role in many recent experiments on the high temperature superconductors in the vicinity of the "strange metal" regime. The Pomeranchuk critical point realizes a metal with a Fermi surface, but no sharp quasiparticle excitations.
I will summarize our current understanding, which draws upon the methods of quantum field theory and holography.
I will conclude with a perspective on the physics of the high temperature superconductors.
The lectures will review key background material on Fermi liquid theory and the theory of phase transitions, and will not assume knowledge of string theory or the AdS/CFT correspondence.

Advanced Workshop on LHC Physics and Cosmology | (smr 2619)
This workshop is designed to complement graduate education, especially in the African countries, and to provide a direct contact to field's leaders in selected research areas, heading towards deep impact research activities. While open to any interested young researchers, it is primarily intended to serve African young academic community. Thus MSc- and PhD-students and Post-Docs (in an early stage of career) from the Southern countries are therefore particularly encouraged to apply.
The LHC is specifically devoted to probe the characterize of the hadronization processes, the properties of the quark-gluon plasma and the origin of the weak scale, so the evolution of the early universe and searches for the various types of matter/radiation/energy filling the background geometry and LHC physics appears to be closely related. Recently, a spectacular progress in astrophysical observations is achieved. It points towards a current era acceleration of our Universe, something that could be explained either by a non-zero cosmological constant in a Friedman-Robertson-Walker-Einstein Universe, or in general by a non-zero dark energy component, which could even be relaxing to zero supporting the geometric interpretation of the acceleration of the Universe today. The accelerating expanding universe has been awarded by the Nobel Prize in Physics in 2010.
The possible constraints on particle physics models, obtained by means of combining the LHC and RHIC with astrophysical data will be reviewed. Issues such as super-symmetric dark matter/energy constraints at LHC, the standard Cosmological-Constant-Cold-Dark-Matter model, superstring-inspired ones and non-equilibrium relaxation dark energy models, the capability of LHC, RHIC, etc. measurements in asserting whether super-symmetric matter constitutes part, or all, of the astrophysical dark matter and prospects for improving the constraints in future precision facilities, such as the International Linear Collider will be discussed. Ultra high energy cosmic rays and their acceleration mechanisms and the associated new physics shall be reviewed. The properties of QGP and latest lattice QCD simulations shall be presented.

Symmetric GAF in de Branges spaces
Given an orthonormal basis {e_n} in a de Branges space (a certain Hilbert space of entire functions), and i.i.d. random variables {a_n} with real normal distribution N(0,1), we consider the Gaussian Analytic Function:
F(z)=\sum_n a_n e_n(z).
In this talk, we will present some results on the distribution of the real zeroes of F(z). It is natural that this random set contains information about the underline Hilbert space. We will see that this information is enough to characterize, up to some nice isomorphism, the de Branges space. We will also show some partial results on the hole probability. We will pay special attention to the Paley-Wiener space, and the spaces associated to the Airy and Bessel functions, because these three spaces also appear in point processes related to random matrices.This talk is based on a joint work with Jordi Marzo and Jan-Fredrik Olsen.

Joint ICTP/SISSA Statistical Physics Seminar: "Old and New Results on the Three Dimensional Ising Model"
We discuss a few old results on the spectrum of the 3d Ising model and on the behaviour of fluid interfaces in the low temperature phase of the model which strongly disagree with the predictions of standard perturbative calculations. Performing a duality transformation (i.e. mapping the 3d Ising model into a Z_2 gauge theory) we show that these apparently puzzling results are signatures of an underlying effective string description of the $Z_2$ gauge model. We then discuss a few recent advances which drastically changed our understanding of these effective string theories and allow to precisely fit both the interface free energy and the low temperature spectrum of the Ising model.

Informal seminar on Chemical Physics: "Non-radiative deactivation mechanisms of electronically excited phenylalanine in model peptides"
Studies of ultrafast non-radiative deactivation (NRD) mechanisms of electronically excited states of small model peptide systems in gas phase, such as N-acetylphenylalaninylamide (NAPA), can provide key insights into the rich photochemistry of proteins, especially the mechanisms responsible for their photostability. We focus on elucidating the NRD pathways of the vibrationless ππ* excited state in three NAPA conformers (βL(a), γL(g+) and γL(g–)) and their conformer dependent excited state lifetime (70, 1.5 and 35 ns, respectively) as observed experimentally.1 Potential NRD pathways were obtained from non-adiabatic molecular dynamics simulations based on modified Tully’s fewest switch algorithm and on-the-fly construction of potential energy surfaces and non-adiabatic couplings using time dependent density functional theory.2 Two mechanisms exhibiting excitation transfer from the phenyl ππ* excited state to nπ* excited states located on each amide group were further refined for all three conformers. This includes the computation of the energy barriers and conical intersection geometries on the coupled cluster (CC2) level of theory for the two mechanisms. By comparing the sizes of the vibrational zero point energy accessible part of the corresponding conical intersection seams, as well as the effects of methyl substitution on the primary amino group, we were able to pinpoint the specific mechanism responsible for the fast NRD processes in the NAPA conformers. In a broader sense, we disclose the structural motifs/motions that control the relaxation dynamics in peptides and hence contribute to preventing their irreversible photochemical damage.3

Large N phase transitions in supersymmetric Chern-Simons theory with massive matter
Abstract: We study supersymmetric U(N) Chern-Simons theory on S3 coupled to 2N_f chiral multiplets deformed by mass terms. The partition function localizes to a matrix integral, which can be exactly computed in the large N limit. In a specific decompactification limit, the theory exhibits quantum (third-order) phase transitions at finite critical values of the coupling.

Joint ICTP/SISSA Statistical Physics Seminar: "Many particle-physics in one dimension: Correlations and dynamics"
Abstract:
This seminar aims to give an introduction to the physics of strongly
correlated fermions and bosons in one-dimension.
I will start from the description of the Tomonaga-Luttinger-Liquid (TLL)
which has been the cornerstone of our understanding of the properties of
one dimensional systems. This universal set of properties plays in one
dimension, the same role than Fermi liquid plays for the higher
dimensional metals. I will give an overview of some of the experimental
tests that were made to probe such TLL physics. In particular I will
detail some of the recent experiments that were made in spin systems and
which provided remarkable quantitative tests of the TLL physics. Than I
will focus on bosons in one-dimension and discuss their properties and
the effects of various perturbations on the Tomonaga-Luttinger liquid
state, as well as extensions to multicomponent and out of equilibrium
situations.
These extensions are specially targeted for the experimental realizations
that have been provided by cold atomic gases in optical lattices.

Lines and pairs of points on cubic hypersurfaces
This is joint work with S.Galkin.
Let X be a cubic hypersurface. We relate the geometry of the symmetric square Sym^2(X) to the Fano varietiy of lines F(X). We work in the Grothendieck ring of varieties, and then take motivic realizations to compare Hodge structure of F(X) to that of X.
Time permitting, I will talk about relation to rationality of a cubic fourfold.

The first part of the talk will aim to motivate slope stability for quivers using GIT via the Hilbert-Mumford criterion. In the second part, we investigate reasonable abelian subcategories of derived categories. Combining these two notions, in a sensible manner, will eventually lead us towards the definition of stability conditions on derived categories.

ICTP School on Applications of Open Spectrum and White Spaces Technologies | (smr 2573)
The Telecommunications/ICT for Development Laboratory (T/ICT4D) of the Abdus Salam International Centre for Theoretical Physics (ICTP, Trieste, Italy), in collaboration with the International elecommunication Union - Telecommunication Development Sector (ITU/BDT), the Network Startup Resource Center (NSRC) and the National Institute of Telecommunications (NIT, Poland), is organising a School on Open Spectrum and Applications of White Spaces Technologies to be held in Trieste from 3 to 14 March 2014.
In the last couple of years a new opportunity for spectrum use has emerged in the form of TV White Spaces (TVWS). Originally conceived as a technology that could take advantage of the guard bands or "white spaces" that were left between television channels to prevent interference, TVWS has the potential to address research challenges of remote academic institutions, as well as opening up alternatives for building community wireless networks.
Traditional spectrum allocation methods are unlikely to be able to cope with the exponential growth in demand for broadband access in emerging markets. There is a pressing need to examine alternative models of spectrum allocation. Dynamic spectrum sharing based on software and cognitive radio can play a significant role in tomorrow's telecommunication systems. With the final goal of connecting Research and Education Centres to the Internet with low cost means to improve Internet access, the School will examine the state of the art in Open Spectrum and TVWS technologies and emerging regulations. The school will address the latest information from TVWS pilots around the world and will include hands-on sessions.
The following key topics will be discussed:
• Radio Physics
• Software Defined Radio
• Cognitive Radio
• Open Spectrum Acess
• TV White Spaces Technologies
Case studies from TV White deployments will be presented.

Joint ICTP/SISSA Statistical Physics Seminar: "Universal Behavior of Shannon and Renyi Mutual Information of Quantum Spin Chains"
In this talk we will first review the Shannon and Renyi entropies as
information theoretic concepts and their use in quantum and classical
systems. They are quantities which usually base dependent. Then we will
introduce mutual Shannon and mutual Renyi entropies as very useful
quantities to detect the universality classes of the quantum spin chains. We
will present some conjectures regarding the connection of these quantities
to central charge of the critical systems and then we will support them with
numerical works done on the Ising model Q=3,4 Potts model and XXZ spin chains.
In all of these cases we will emphasize on the bases that one
chooses to calculate these quantities and in particular we will show that
some of the bases are actually more suitable to detect the universality
classes.

Workshop on Advanced Techniques for Scientific Programming and Management of Open Source Software Packages (10-21 March), followed by LAMMPS Users and Developers Workshop and Symposium (24-28 March) | (smr 2574)
The Abdus Salam International Centre for Theoretical Physics is organizing a Workshop on Advanced Techniques for Scientific Programming and Management of Open Source Software Packages, to be held at ICTP (Trieste, Italy) from 10 to 21 March 2014, followed by a one-week LAMMPS Users and Developers Worskhop and Symposium.
Modern scientific research work involves using computers for simulation, modeling, data processing and visualization. The growing complexity of those calculations favors using software packages that provide an abstract interface to computations through scripting language interfaces, modular software design, and code reuse. Such design patterns also facilitate transparent optimizations for modern multi-core architectures or accelerators, and specialization of contributors to subsets of a package program. Software package developers therefore need to learn how to work effectively in a collaborative environment.
This Hands-on Workshop focuses on disseminating best practices and building fundamental skills in creating, extending and collaborating on modular and reusable software frameworks with a scripting language interface. The curriculum also covers using modern collaborative software management tools, testing frameworks, and embedding structured documentation into software packages.
The optional LAMMPS Users and Developers Workshop and Symposium during the third week takes the LAMMPS Molecular Dynamics package as an example and provides specialized training for computational scientists that already are or want to become LAMMPS developers. The training will consist of lectures on the LAMMPS software overall design and implementation details as well as hand-on tutorial sessions by LAMMPS experts and developers.

Joint ICTP/SISSA Statistical Physics seminar: "Universal quantum simulator, local convertibility and edge states in many-body systems"
In some many-body systems, certain ground state entanglement (Renyi) entropies increase even as the correlation length decreases. This entanglement non-monotonicity implies a stronger "quantum nature" of the wave function and gives it a higher computational power, compared to classical manipulations. We will demonstrate that such a phenomenon, known as non-local convertibility, is due to the edge state (de)construction occurring in the system. To this end, we employ the example of the Ising chain, displaying an order-disorder quantum phase transitions. Employing both analytical and numerical methods, we compute entanglement entropies for various system's bipartitions (A|B) and consider ground states with and without Majorana edge states. We find that the thermal ground states, enjoying the Hamiltonian symmetries, show non-local convertibility if either A or B are smaller than, or of the order of, the correlation length. In contrast, the ordered (symmetry breaking) ground state is always locally convertible. The edge states behavior explains all these results and could disclose a paradigm to understand local convertibility in other quantum phases of matter. The connection we establish between convertibility and non-local, quantum correlations provides a clear criterion of which features a universal quantum simulator should possess to outperform a classical machine.

Joint ICTP/SISSA Statistical Physics Seminar: "Precision Measurements of Temperature and Chemical Potential of Quantum Gases"
We investigate the sensitivity with which the temperature and the chemical potential characterizing quantum gases can be measured. We calculate the corresponding quantum Fisher information matrices for both fermionic and bosonic gases. For the latter, particular attention is devoted to the situation close to the Bose-Einstein condensation transition, which we examine not only for the standard scenario in three dimensions, but also for generalized condensation in lower dimensions, where the bosons condense in a subspace of Hilbert space instead of a unique ground state, as well as condensation at fixed volume or fixed pressure. We show that Bose Einstein condensation can lead to sub-shot noise sensitivity for the measurement of the chemical potential. We also examine the influence of interactions on the sensitivity in three different models, and show that mean-field and contact interactions deteriorate the sensitivity but only slightly for experimentally accessible weak interactions.

Tropical and Enumerative Geometry
Tropical geometry has nowadays several, different facets related to algebraic gometry, commutative algebra, symplectic geometry, optimization, low-dimensional topology, knot theory and physics.
In the context of enumerative geometry the idea is to replace objects from algebraic geometry by combinatorial objects, we say we tropicalize these objects. The key feature of tropicalization is that important information about the objects (related to the problem studied) is conserved.
After a recap of basic notions, I will give an overview of recent achievements of tropical enumerative geometry and discuss current directions of research.

The Workshop constitutes a unique opportunity for scientists to gain extensive and up- to-date training on the evaluation of nuclear structure and decay data, as developed to produce the Evaluated Nuclear Structure Data File (ENSDF) and Nuclear Data Sheets for use and adoption by the nuclear physics community. Reliable evaluated nuclear structure and decay data are of vital importance in a large number of energy and non- energy based applications such as power generation, materials analysis, dosimetry and medical diagnostics, as well as basic nuclear physics and astrophysics. Important features of these needs are satisfied by the work undertaken by the International Network of Nuclear Structure and Decay Data (NSDD) Evaluators. The main products of this worldwide network are the recommended data files and evaluated decay data.

Seminar on Disorder and strong electron correlations: "Charge transport: The rise of the helical modes"
Helical modes, in which the momentum and spin quantum numbers are strongly coupled, have recently appeared in the front line of one-dimensional physics through the discovery of materials exhibiting the quantum spin-Hall effect. The fascinating conduction properties of the edge states of such materials is determined not just by the naturally strongly correlated nature of one-dimensional quantum systems, but also through the helical nature of such modes.
In this presentation, I will consider two examples of helical modes. The first arises in the edge states of the quantum spin-Hall effect, where I will consider how the helical structure of the states influences the Kondo effect when one traps a single spin within a double constriction. The second example appears when domain walls are induced into the quantum Hall state of bilayer graphene under appropriate gating. I will demonstrate that one-dimensional helical modes form on this kink, which may then be tuned through a quantum phase transition in the Z_2 universality class. The helical nature of the modes means the two phases on either side of this transition have distinct conducting properties, in particular one is superfluid and the other is insulating.

Seminar on Disorder and strong electron correlations: "Giant magnetodrag in graphene at charge neutrality"
We report experimental data and theoretical analysis of Coulomb drag between two closely positioned graphene monolayers in a weak magnetic field. Close enough to the neutrality point, the coexistence of electrons and holes in each layer leads to a dramatic increase of the drag resistivity. Away from charge neutrality, we observe nonzero Hall drag. The observed phenomena are explained by decoupling of electric and quasiparticle currents which are orthogonal at charge neutrality. The sign of magnetodrag depends on the energy relaxation rate and geometry of the sample.

Conference on Open-source Tools for Enhancing Teaching, Learning and Research in Science, Technology, Engineering and Mathematics (STEM) | (smr 2508)
The Abdus Salam International Centre for Theoretical Physics is organizing, in collaboration with the Universidad Nacional Autonoma de Honduras, a Conference on Open-Source Tools for Enhancing Teaching, Learning and Research in Science, Technology, Engineering and Mathematics (STEM) disciplines to be held in Tegucigalpa, Honduras from 6 to 11 April 2014.
INTRODUCTION A growing trend in educational institutions is the use of various electronic and other computer based aids as tools for enhancing the teaching and learning experience. From simple electronic aids such as presentation slides, web based learning management systems and more complex audio-video based learning/collaborative systems are now widely used in many scientific and academic environments. This conference brings together scientists and educators with an aim on sharing experiences along-side practical demonstrations of various open-source tools/techniques for enhancing teaching, learning and research in the STEM disciplines.
TOPICS TO BE COVERED DURING THE ACTIVITY INCLUDE:
•Introduction to e-learning
•Tools for enhancing course management.
•Tools for enhancing teaching
•Tools for enhancing collaborative learning
•Tools for enhancing grading (assignments, tests and examinations)
•Tools for enhancing practical laboratory work
PARTICIPATION
This activity is aimed primarily at scientists, educators and other support staff that currently use or plan to deploy electronic or computer based tools/aids in supporting teaching, learning and research in a STEM discipline. Participants from all countries, which are members of the United Nations, UNESCO or IAEA, may attend the workshop, however, since this is a regional activity, priority will be given to applicants coming from the region.
As the School will be conducted in English, participants should have an adequate working knowledge of that language. Although the main purpose of the Centre is to help research workers from developing countries through a programme of training activities within a framework of international cooperation, a limited number of students from developed countries are also welcome to attend. As a rule, travel and subsistence expenses of the participants should be borne by their home institutions. Every effort should be made by candidates to secure support for their fare (or at least half fare). However, limited funds are available for some participants, who are nationals of, and working in, a developing country, and who are not more than 45 years old. Such support is available only to those attending the entire activity. There is no registration fee.

Constraints on light dark sector particles from White Dwarfs and Supernovae
Abstract. Theories with a dark sector, that communicates with the visible sector only via U(1) kinetic mixing, are interesting because they could provide an explanation for dark matter. If the dark sector contains light particles, these could be produced in the interior of a star and accelerate its cooling. I show that, considering the well-understood cooling laws of white dwarfs and supernovae, one can place significant constraints on these models.

A homotopy-theoretic approach to some theorems in arithmetic.
The theorems in the title refer to some generalizations and consequences of the quadratic reciprocity law. These all play on how the various finite rings Z/nZ, which are simple to understand by themselves, are tied together by the more complicated ring Z. I will give an introduction to these types of theorems, and then indicate how a certain homotopy-theoretic construction relating tori and spheres can be used to provide proofs of some of them, starting with the quadratic reciprocity law itself.

Spinning Fluids: A Group Theoretical Approach
Abstract: We will review a group theoretical fluid model to describe gauge interactions. In particular we will focus on QGP physics applications describing how it is possible to reproduce the chiral magnetic effect and study similar effects through this formalism. Other than gauge groups this formalism can be used to describe any dynamics completely described by a symmetry group. We will show how to use this formalism to write a Mathisson-Papapetrou equation for spinning relativistic fluids.

Momentum dissipation and charge transport in holography
Abstract. Holography can be used to study the physics of strongly coupled quantum field theories at finite density, which may be at work in certain real materials. However, the conservation of momentum in these field theories means that they have unrealistic transport properties, such as an infinite electrical conductivity. I will give a summary of recent progress in constructing gravitational solutions which are dual to field theories which dissipate momentum. I will explain how these gravitational solutions are related to theories of massive gravity, and what the transport properties of the dual field theories are. Finally, I will describe a simple mechanism, which is natural from the holographic point of view, by which strongly interacting metals can acquire a linear in temperature resistivity, as is observed in the strange metal phase of the cuprates.

Joint ICTP-IAEA College on Identification and Assessment of Nationally Appropriate Mitigation Actions (NAMAs) in Energy System Development to Help Combat Climate Change | (smr 2580)
The purpose of this college is to address the capability gap that exists in many developing countries and help build necessary expertise to identify NAMAs in the energy system development and to assess their effectiveness in combating climate change. As the major source of GHG emissions, the energy system will inevitably be affected by international environmental agreements targeted at avoiding dangerous anthropogenic interference with the climate system. Since over two-thirds of the projected increase in world energy demand is expected to occur in developing countries, their energy technology choices and investment decisions will have considerable impact on the international efforts towards mitigation of climate change. As an important contribution to these efforts, the international community under UNFCCC has agreed that developing countries submit (voluntary) plans on National Appropriate Mitigation Action (NAMA) aimed at avoiding/reducing future GHG emissions. Hence, there is a need not only to identify and evaluate cost-effective NAMAs but also to better understand the challenges and opportunities for the development of energy systems under alternative and/or complementary response actions to climate change at national and international levels. Reconciling the national actions on climate and policies on energy with international targets is extremely challenging. During the college the above themes will be addressed through a series of lectures and hands-on laboratory classes using state-of-the-art modelling tools.
Topics include: Energy options and climate change threats, Major issues in equitable international climate regime, Scientific uncertainties and their impact on energy and climate policy formulation, Methods for assessment of Nationally Appropriate Mitigation Actions

Seminar: " From metadynamics to dynamics "
Metadynamics is a commonly used and successful enhanced sampling method. By the introduction of a history dependent bias which depends on a restricted number of collective variables it can explore complex free energy surfaces characterized by several metastable states separated by large free energy barriers. We recently extended its scope by introducing a simple yet powerful method for calculating the rates of transition between different metastable states. The method does not rely on a previous knowledge of the transition states or reaction coordinates, as long as collective variables are known that can distinguish between the various stable minima in free energy space. A statistical analysis of the distribution of transition times allows us to verify a posteriori the reliability of our calculations, and if any relevant slow collective variables are missing. We apply our method to a number of examples of increasing complexity. We find excellent agreement between our calculations and the results of long unbiased molecular dynamics simulations whenever the latter are feasible.

Joint ICTP/SISSA Statistical Physics Seminar: Conformal Invariance of Critical Fluctuations in d=3
Abstract:
It has been conjectured in 1971 by Polyakov that critical phenomena
have conformal invariance, both in two and three dimensions. While the
two dimensional case has been intensely studied, the role of conformal
invariance in d=3 is not fully clarified. We will describe which parts
of conformal field theory carry over from d=2 to d=3. We will describe
the `conformal bootstrap' equations, whose solutions should give
conformally invariant algebras of local operators in d=3. The simplest
case is the operator algebra corresponding to the critical point of
the 3d Ising model. We conjecture that this operator algebra can be
characterized by a minimal central charge condition. Numerical
evidence for this conjecture will be presented. (based on
arxiv:1403.4545).

Seventh ICTP Workshop on the Theory and Use of Regional Climate Models | (smr 2581)
Regional climate models (RCMs) are widely used tools to produce high resolution climate simulations at regional scales. The ICTP regional climate modeling system, RegCM, is one of the most used RCMs worldwide, with applications ranging from regional process studies to paleoclimate, climate change, chemistry-climate and biosphere-atmosphere interactions. A new version of the model, RegCM4, has been completed and released in 2012, but new features are being included for release during this workshop, such as the CLM4.5 land surface scheme, a new cloud microphysics scheme and coupling with the MIT Ocean model. As in previous workshops of this series, this event will provide lectures and extensive hands-on sessions on the theory of regional climate change and regional climate modeling as well as on the use of the RegCM4 modeling system. The focus of the present workshop will be on the application of the RegCM4 within the international program CORDEX (COordinated Regional Downscaling EXperiment. The primary aim of CORDEX is to produce a new generation of large multi-model ensembles of regional climate change projections over domains covering all continental areas of the world for use in impact assessment and adaptation studies. The RegCM community contributes to CORDEX through the completion of numerical experiments over different CORDEX domains. The workshop is thus intended to provide a forum to assess and intercompare these experiments within the context of the goals of CORDEX. The workshop is also aimed at providing a forum for current and future model users to discuss relevant issues and formulate needs and priorities for further model development and dissemination. A limited number of participants is envisioned, with proven experience in climate modeling and a strong interest in using the RegCM4 system for regional climate studies.

Pre-Inflationary Clues from String Theory?
Abstract. "Brane supersymmetry breaking'' occurs in String Theory when the only available combinations of D--branes and orientifolds are not mutually BPS and yet do not introduce tree--level tachyon instabilities. It is characterized by the emergence of a steep exponential potential, and thus by the absence of maximally symmetric vacua. The corresponding low--energy supergravity admits intriguing spatially--flat cosmological solutions where a scalar field is forced to climb up toward the steep potential after an initial singularity, and additional milder terms can inject an inflationary phase during the ensuing descent. We show that, in the resulting power spectra of scalar perturbations, an infrared suppression is typically followed by a pre--inflationary peak that reflects the end of the climbing phase and can lie well apart from the approximately scale invariant profile. A first look at WMAP9 raw data shows that, while the chi-squared fits for the low--l CMB angular power spectrum are clearly compatible with an almost scale invariant behavior, they display nonetheless an eye--catching preference for this type of setting within a perturbative string regime.

Seminar on Disorder and strong electron correlations: "Fluctuation-induced first-order quantum phase transition of the U(1) spin liquid in a pyrochlore quantum spin ice"
We predict, using a free-energy calculation, that the quantum phase transition between the U(1) quantum spin liquid (QSL) and antiferromagnet (AFM) phases in certain pyrochlore quantum spin ice is first order rather than second order. This change in order from second to first order is induced by gauge fluctuations, which are explicitly taken into account at gauge theory level in our effective low-energy theory. We therefore have identified a fluctuation-induced first-order quantum phase transition in pyrochlore quantum spin ice. We explicitly derive the quantum free-energy description of this QSL-to-AFM phase transition and predict that it is a weakly first-order phase transition. We also briefly discuss the experimental relevance of this result.

The Abdus Salam ICTP and SISSA, in collaboration with the partner institutions of the Master in the Physics of Complex Systems (http://www.polito.it/pcs) will organize the Spring College on the Physics of Complex Systems from 26 May to 20 June 2014.
Many complex systems in physics, biology, engineering and economics are characterized by a large number of interacting degrees of freedom giving rise to a non-trivial collective behavior. The theoretical and computational tools for a quantitative analysis of complex systems are often rooted in modern (statistical, quantum) physics. The Spring College on the Physics of Complex Systems aims
to give students the opportunity to get in touch with a selection of topics at the forefront of research, during an intensive 4-week program. It consists of 5 courses of 9 lectures each, followed by final written tests.

Workshop on Internet of Things | (smr 2686)
IoT describes a system where items in the physical world, and sensors within or attached to these items, are connected to the Internet via wireless and wired Internet connections.
These sensors can use various types of local area connections such as RFID, NFC, Wi-Fi, Bluetooth, and Zigbee. Sensors can also have wide area connectivity such as GSM, GPRS, 3G, and LTE.
The physical objects that are being connected will possess one or more sensors. Each sensor will monitor a specific condition such as location, vibration, motion and temperature. In IoT, these sensors will connect to each other and to systems that can understand or present information from the sensor’s data feeds. IoT data differs from traditional computing. The data can be small in size and frequent in transmission.
The number of devices, or nodes, that are connecting to the network are also greater in IoT than in traditional PC computing. Machine-to-Machine communications and intelligence drawn from the devices and the network will allow businesses to automate certain basic tasks without depending on central or cloud based applications and services.
These attributes present opportunities to collect a wide range of data but also provide challenges in terms of designing the appropriate data networking and security.

On Spin and Long Range Forces: Continuous Spin Particles Demystified
Abstract: The success of gauge theory descriptions of Nature follows simply, in hindsight, from Lorentz symmetry, quantum mechanics, and the existence of interacting massless particles with spin. Yet, remarkably, the most generic type of massless particle spin has never been seriously examined: Wigner's so-called "continuous spin" particles (CSPs), which have a tower of polarization states carrying all integer or half-integer helicities that mix under boosts. In this talk, I will explain how to think about CSPs, and some hints from the symmetry constraints on scattering amplitudes not only that CSP theories may be consistent, but that they could be relevant to understanding long-range forces in Nature. Further progress in understanding free CSPs in field theory will be discussed in Philip Schuster's seminar to follow.

Continuous Spin Particles In Field Theory
Abstract: Spin characterizes how particle states re-phase under changes of frame that leave their momentum and energy invariant. But all familiar field theories propagate particles that transform trivially under some of these transformations --- in particular, those that involve boosts. For example, until very recently it was not known how to describe the four-dimensional "continuous spin'' particles (CSPs) in field theory. In this talk, I will introduce a new covariant, local action for gauge fields, whose physical excitation in four dimensions is a CSP. The theory is simply formulated as a gauge theory in a "vector superspace", but can also be formulated in terms of a tower of symmetric tensor gauge fields. In the limit of vanishing spin-scale Ï, the theory smoothly recovers familiar gauge-theory actions. The theory readily generalizes to higher or lower dimensions; in 2+1 dimensions, the only kind of massless particle with non-trivial physical spin is CSP-like. These "panyons" can be understood as massless generalizations of anyons, but are simpler in key respects.

Joint ICTP/SISSA INFORMAL SEMINAR on Statistical Physics: "Space Use by Foragers with Renewable Resources"
Abstract:
We are participating in a project to study and understand a keystone mutualistic system in the Patagonian temperate forest. It is composed of two specialist partners: a small arboreal marsupial that feeds on the fruits of a hemiparasite shrub and disperses it seeds. As part of this effort we have described the movement of the animals in a heterogeneous landscape as a walk that dynamically affects its substrate.
Our simplest model provides an insight on a number of relevant and non-intuitive facts. Even without memory of the good places to feed and no explicit cost of moving, we observe the emergence of a finite home range. The reason for this is that memory of the usage of the landscape is kept in the landscape itself. The arising paths looks surprisingly similar to real animal tracks. We characterize this walks and their use of the resources in several statistical ways. Preliminary results on population effects are explored by means of a system of two non (directly) interacting animals.
This work is a first step towards a complex model that will take into consideration the interaction between plants and seed dispersers and the synergistic effect that arises from their mutualistic interaction. Despite its inspiration on a very specific system, this first step is of very general application and may be of interest in other contexts.

Dark Energy, QCD axion, and Comment on BICEP2
Abstract. I will briefly talk on approximate global symmetries which can be a dark energy symmetry and PQ symmetry. These are constructed such that there is no gravity spoil of global symmetries. For the QCD axion, it is suggested to use the anomalous U(1) symmetry from string compactification, which gives a domain-wall number 1 models.

Joint ICTP-TWAS School on Coherent State Transforms, Time-Frequency and Time-Scale Analysis, Applications | (smr 2585)
The topics of this school are coherent states, wavelets and their applications (signal/image processing via Gabor and wavelet analysis, inverse problems, approximation theory), plus necessary concepts of functional analysis and group theory. Coherent states and wavelets are two topics that have undergone a tremendous development in the last years, it is an extremely active domain. They have applications in a huge number of domains of physics, mathematics and engineering. This school, that will present many of the topflight experts in the field, will enable young scientists to catch on that fascinating topic and obtain a knowledge suitable for performing top level research. We plan to go from the basic aspects to up-to-date developments and also to cover some of the most exciting applications, such as inverse problems, analysis of geophysical, astronomical or biological (genome) signals.
Coherent states and wavelets are domains where top level research can be done in small, somewhat isolated places, contray to high energy physics, for instance. They are based on beautiful (also applied) mathematics and have applications in a huge variety of domains. In addition, they allow to perform excellent research with small computing equipments, which make them suitable for researchers from developing countries.
The Main Topics
● Basic theory of coherent states, in particular the group-theoretical background
● Gabor analysis with applications
● Wavelet analysis, both continuous and discrete, with applications
● Recent developments, such as curvelets, shearlets, compressed sensing, co-orbit theory or
wavelets on graphs

Informal seminar on Chemical Physics: "Ensemble approaches to the computer simulation of site-disordered solids"
Site-occupancy disorder, defined as the non-periodic occupation of lattice sites in a crystal structure, is a ubiquitous phenomenon in solid-state physics and chemistry. Examples are mineral solid solutions, synthetic non-stoichiometric compounds and metal alloys. The experimental investigation of these materials using diffraction techniques only provides averaged information of their structure. However, many properties of interest in these solids are determined by the local geometry and degree of disorder, which escape an “average crystal” description, either from experiments or from theory. In this talk, I will introduce a methodology for the computer simulation of site-disordered solids, based on the consideration of configurational ensembles and statistical mechanics [1, 2]. The number of occupancy configurations is reduced by taking advantage of the crystal symmetry of the lattice. Thermodynamics and non-thermodynamic properties are then defined from the statistics in the symmetry-adapted configurational ensemble. I will briefly discuss some recent applications of this methodology and of its generalization to grand-canonical ensembles [3-7].

Joint ICTP-IAEA Workshop on Determination of Uncertainties of Measurements in Medical Radiation Dosimetry | (smr 2616)
The aim of this Workshop is to familiarize physicists, working in radiation dosimetry laboratories or lecturers teaching radiation dosimetry, with procedures and methodologies that should be utilized for the determination of uncertainties in medical radiation dosimetry.
Contrary to earlier practice, when the terms error and uncertainty were used interchangeably, the modern approach distinguishes between these two concepts. Traditionally, an error has been viewed as having two components, namely a random component and a systematic component. According to present definitions, an error is the difference between a measured value and the true value. If errors were known exactly, the true value could be determined; in reality, errors are estimated in the best possible way and corrections are made for them. Therefore, after application of all known corrections, errors do not need any further consideration and the quantities of interest are uncertainties. An error has both a numerical value and a sign. In contrast, the uncertainty associated with a measurement is a parameter that characterizes the dispersion of the values “that could reasonably be attributed to the measurand”.
This parameter is normally an estimated standard deviation. An uncertainty, therefore, has no known sign and is usually assumed to be symmetrical. It is “a measure” of our lack of exact knowledge, after all recognized systematic effects have been taken into count by applying appropriate corrections.
Uncertainties of measurements are expressed as relative standard uncertainties and the evaluation of standard uncertainties is classified into type A and type B. The method of evaluation of type A standard uncertainties is by statistical analysis of a series of observations, whereas the method of evaluation of type B standard uncertainties is based on means other than statistical analysis of a series of observations.
The IAEA, understanding the need to provide practical guidance on the estimation of measurement uncertainty in dosimetry, has incorporated a specific section on this topic in relevant publications on radiation dosimetry, such as the IAEA TRS-398 (Absorbed Dose Determination in External-Beam Radiotherapy An-International Code of Practice for Dosimetry Based on Standards of Absorbed dose toWater), IAEA TRS-454 (Quality Assurance for Radioactivity Measurement in Nuclear Medicine), IAEA TRS-457 (Dosimetry in Diagnostic Radiology: An International Code of Practice) and IAEA TEC DOC-1585 Measurement Uncertainty: A Practical Guide for Secondary-Standards Dosimetry Laboratories).

Poincaré Theory for compact abelian one-dimensional solenoidal groups
Abstract: The notion of Poincaré rotation number for homeomorphisms of the unit circle is generalized to the case of homeomorphisms of a general compact abelian one–dimensional solenoidal group, which is also a one–dimensional foliated space; specifically, the theory is developed for the algebraic universal covering space of the circle (the adèle class group of the rationals). Poincaré’s dynamical classification theorem is also generalized to homeomorphisms of solenoids whose rotation element is an irrational element (i.e., monothetic generator) of the given group.

Electromagnetic response of strongly coupled plasmas
Abstract: I briefly present a thorough analysis of the electromagnetic response of strongly coupled neutral plasmas described by the gauge/gravity correspondence. The coupling of the external electromagnetic field with the tower of quasi-normal modes of the plasmas supports the presence of various electromagnetic modes with different properties. Among them we underline the existence of negative refraction with low dissipation for a transverse non-hydrodynamical mode. Previous hydrodynamical approaches have shown the ubiquitous character of negative refraction in charged plasmas and the absence thereof in neutral plasmas. The results I present here extend the analysis to neutral plasmas beyond the hydrodynamical regime. As an application of these new insights, I will succinctly discuss the case of the quark gluon plasma in the temperature dominated regime.

ICTP-IITM-COLA Targeted Training Activity (TTA): "Challenge in Monsoon Prediction" | (smr 2589)
Since 2004, the ICTP Earth System Physics section has conducted “Targeted Training Activity (TTA),” a specialized educational activity with a team-oriented nature. This team-oriented aspect is aiming to develop groups of scientists who can work together on a specific goal within a developing-country institution. Previous TTAs on the seasonal predictability in tropical regions have been successful to initiate seasonal climate prediction researches and contributed to operational application in the developing countries. The topic of the TTA 2014 will be the challenges in monsoon prediction. Current state-of-the-art seasonal prediction systems show some skill in predicting the variations of the monsoons at various lead times, ranging from weeks to months. However, this prediction skill is still much lower that the potential prediction skill that may be estimated form models and theoretical estimates. Indeed, it seems that predictive skill for seasonal predictions in many monsoon regions stems exclusively from the correct prediction of ENSO several months ahead. The aim of the TTA 2014 is to explore the scientific bases of potential other sources of predictability, such as Indian Ocean, West Pacific and Atlantic SSTs. Further sources of predictability may be related to land-surface condition, snow cover (in case of Indian monsoon), wave propagation from the extratropics as well as aerosols. The workshop aims at addressing all of these topics in lectures in the mornings and, with lab-sessions in the afternoons.

Workshop on the Economy of a Cell: Resource Allocation, Trade-Offs and Efficiency in Living Systems | (smr 2588)
The Abdus Salam International Centre for Theoretical Physics (ICTP, Trieste, Italy) is organizing the above workshop to take place at the ICTP from 23 to 27 June 2014.
In recent years the dynamics of biological systems has been increasingly described using concepts and terminology borrowed from economics: cells face trade-offs between different strategies for survival; the generation of proteins from DNA displays multiple levels of subtle, optimal efficiency; metabolism can be viewed as a resource allocation problem; biomolecules can be associated with a “value” within the free energy “market” of the cell. These concepts indicate the emergence of a new way of thinking about problems in biology. We envisage that innovation in several important areas of biology can ensue from exploring in more depth and in a more coherent way this connection between cellular dynamics and concepts traditionally used in economics.
The purpose of this workshop is to bring together systems biologists and physicists whose research has brought them to an economy-inspired view of the cell. Scientists from different backgrounds will discuss biological questions that can be addressed using concepts of resource allocation, efficiency and optimality. The following topics will be covered:
(1) Genome-scale cellular metabolism and the global molecular budget of a cell;
(2) The economy of gene expression and protein synthesis: the cellular adaptations to translational
efficiency;
(3) Benefits and costs in cellular fitness;
(4) Trade-offs and Pareto-optimality
in biological systems;
(5) Game theory in cellular and multicellular biology; and
(6) Economics of cognitive-like processes at the cellular level.

SPECIAL PUBLIC LECTURE
"On explicitly solvable ODE's"
Abstract
We discuss the problem of integration of ODE systems by quadratures. The main classical results on exact integration of general nonlinear systems are the Euler-Jacobi theorem on the integrating factor and the Lie theorem on the solvable algebra of symmetries. We present a general theory uniting these two approaches.
We generalize Darboux's classical results on the integrability of linear non-autonomous systems with an incomplete set of particular solutions. Special attention is paid to linear Hamiltonian systems.
We also discuss the general problem of integrability of autonomous ODE systems in an n-dimensional space which admit an algebra of symmetry fields of dimension greater than or equal to n.

Conference on Non-equilibrium Phenomena in Condensed Matter and String Theory | (smr 2590)
The Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy, is organizing a Conference on Non-Equilibrium Phenomena in Condensed Matter and String Theory, to be held in Trieste from 30 June to 4 July 2014.
Small fluctuations of systems at equilibrium or weakly driven near equilibrium satisfy a universal relation known as the fluctuation-dissipation theorem, which connects spontaneous fluctuations to the linear response. The search for similar relations for systems far from equilibrium has been an important problem for many years with applications in Condensed Matter and Atomic Molecular Optical systems, as well as ion collisions at Relativistic Heavy Ion Collider and at Large Hadron Collider.
Presently, many important questions remain unanswered, such as identifying the relevant time scales for relaxation and thermalization, finding whether there is an equivalent of the KAM theorem for quantum systems, understanding the effect of disorder and driving, among others. Making progress on those questions will require a close collaboration between experimentalists and theorists, as well as a the exchange of ideas and approaches between different fields.
This Conference will help catalyze interactions between the Condensed Matter/AMO physicists working on problems far from equilibrium with their counterparts in the High Energy physics community. It will also allow interested scientists to enter this exciting new area of research through a daily pedagogical talk.

QUANTITATIVE BIOLOGY SEMINAR: "Gyrotactic Phytoplankton Swimming in a Flow"
Many aquatic microorganisms are able to swim and typically do it in a moving, sometimes turbulent, fluid environment. The interaction between swimming (self-propulsion) and flow advection can give rise to interesting phenomenology, especially concerning the spatial distribution of microbes. Many aspects of such interaction can be understood by using ideas and tools from dynamical systems theory and fluid mechanics. Here we shall discuss some of these aspects focusing on the case study of gyrotactic phytoplankton, which swims by means of two flagella opposite to the center of mass, which is displaced with respect to the center of symmetry --- bottom heavy cells.

Joint ICTP/SISSA Statistical Physics Seminar: "Quantum Quenches in the XXZ Spin Chain and the Generalized Gibbs Ensemble"
Isolated integrable quantum systems do not relax to a thermal state even locally due to the extra conserved quantities that they possess. The so-called Generalized Gibbs Ensemble (GGE) was proposed to capture the steady state of integrable systems, but it has not been put to a stringent test for genuinely interacting systems.
In the talk I will review our work on the non-equilibrium time evolution of the spin-1/2 anisotropic Heisenberg (XXZ) spin chain, where we found that short-ranged spin correlators in the long-time limit deviate significantly from predictions based on the GGE hypothesis. By computing the asymptotic spin correlators within the quench action formalism based on exact overlaps, however, we find excellent agreement with the numerical data. I will show why this result can be considered as conclusive evidence for the failure of the GGE and I will discuss the possible implications of this finding.

QUANTITATIVE BIOLOGY SEMINAR: "Simple Behavior of Complex Biological Networks"
Recent high-precision and high-throughput measurements of biological networks dynamics have uncovered interesting results. Namely, many biological systems appear to be critical (so that their dynamics can be classified into a handful of universal classes), or are described with high accuracy by surprisingly simple, phenomenological models. I will explore a handful of simple theoretical models inspired by these observations, suggesting plausible explanations for this emergence of coarse-grained simplicity from complex microscopic structures.

Scattering amplitude of the Chern-Simons theory with matter
(& the study of Bose-Fermi duality)
Abstract: In case of Chern-Simons matter theories, the charged particle itself is regarded as the magnetic flux, then it exhibits a lot of "strange behavior" which will not be understood with our intuition based on the Maxwell equation. In this talk, we studied how such a "strange" feature of the Chern-Simons matter theory affects the usual S-matrix analysis. We have also studied the duality relationship between Bosonic system and Fermionic system based on the result of the S-matrix.

QUANTITATIVE BIOLOGY SEMINAR: "Fluxes, Scaling and Dimensions in Fully Developed Turbulence"
In this seminar, I will discuss a few important open problems in 'Fully Developed Turbulence' concerning its most idealised realisation, i.e. the case of statistically homogeneous and isotropic flows. I will discuss the importance of inviscid conserved quantities in relation to the most striking statistical properties shown by all turbulent flows: the growth of small-scale strongly non-Gaussian fluctuations, including the presence of anomalous scaling laws. By using unconventional numerical methodology, based on a Galerkin decimation of helical Fourier modes, I will argue that some phenomena characterising homogeneous and isotropic flows might be important also for a much larger spectrum of applications, including flows with geophysical and astrophysical relevance as for the case of rotating turbulence and/or conducting fluids.

WCRP-ICTP Summer School on Attribution and Prediction of Extreme Events | (smr 2595)
The Abdus Salam International Centre for Theoretical Physics (ICTP) is orgamzmg, in collaboration with the World Climate Research Programme (WCRP), a Summer School on Attribution and Prediction of Extreme Events, to be held at ICTP, Trieste (Italy), from 21 July to 1 August 2014.
PURPOSE OF THE SCHOOL
The purpose of the School is to train students with outstanding research potential in the techniques that will be required to better understand observed and future changes in extremes. There is a pressing need to educate future researchers in the techniques given the prominence and importance of societal and scientific questions about extreme events that are receiving increasingly intense attention in the minds of the public and their policy makers. The School will be organized around three broad topic areas:
• Statistical theory underpinning extreme value analysis;
• Detection and attribution of observed changes in the frequency and/or intensity of extremes;
• Event attribution, and the physical mechanisms that are involved in amplifying and/or extending the duration of some specific extreme events such as heat waves.
The School will also educate students in the development of some of the key data resources that are used to place current extremes into a historical context, and will provide insights into some of the emerging thinking on the near term prediction of the likelihood of extreme events.
The School will also teach the importance of understanding the physical mechanisms that produce many of the most impactful extreme events, including "complex" hydrologic extremes such as drought and the role of coupled land-atmosphere feedback mechanisms in amplifying extreme temperature events.
FORMAT
The two-week School will consist of lectures combined with the practical application of the material covered in the lectures through introductory lab sessions and a set of research problems that will form the core of the School. The research topics will include data set development, detection and attribution, extreme events prediction, and event attribution. These will rely on the use of the advanced analysis techniques that will be taught at the School and an understanding of the relevant underpinning physical processes.

School on Computation and Computability in Dynamics | (smr 2684)
Topic: Computational methods, computability and computer aided proofs in dynamics with a special focus on statistical and ergodic properties. The understanding and forecasting of statistical properties of a dynamical model is a central topic in the modern theory of dynamical systems and in the applications. Computers already helps much in this understanding. This gives a strong motivation to the study of the theoretical limits of such computations and to the development of new methods and algorithms for the rigorous computation, where the reliability of the result is certified.

Joint ICTP/SISSA Statistical Physics Seminar: "New Results for Quantum Antiferromagnets in High Magnetic Fields"
Frustrated antiferromagnets are a very rich class of physical systems, in which various new phases of matter are expected to be realized. From a theoretical point of view, however, they present challenging difficulties and typically defy a full quantum treatment. A possible strategy is to restrict oneself to a specific region of the parameter space, namely the one of high applied magnetic field, where the problem can be mapped to a dilute Bose gas of magnons. In this way we can provide benchmarks for the latest numerical approaches, such as in the case of the prototypical spin-1/2 XXZ model on the triangular lattice [1]. In more complicated models with competing exchange interactions, we find new types of magnetic order, such as a double-q state with striped chiral order [2]. Several problems remain open in this field-theoretical approach, in particular three-magnon and four-magnon scattering amplitudes, which relate to a recently discovered magnetic "0-pi" phase transition and to the stability of the spin nematic phase respectively.

Discrete cosmology: mechanical approach to the late-time Universe
Abstract: We consider the Universe deep inside the cell of uniformity which is of the order of 190 Mpc. At these scales, the Universe is filled with inhomogeneously distributed discrete structures (galaxies, groups and clusters of galaxies), which perturb the background Friedmann model. Here, the mechanical approach is the most appropriate to describe the dynamics of the inhomogeneities which is defined, on the one hand, by gravitational potentials of inhomogeneities and, on the other hand, by the cosmological expansion of the Universe. As an example, we consider the collision between the Milky Way and Andromeda in future.

Turbulent Mixing and Beyond Workshop: Mixing in Rapidly Changing Environments - Probing Matter at the Extremes | (smr 2596)
The Abdus Salam International Centre for Theoretical Physics (ICTP, Trieste, Italy) is organizing a Workshop “Mixing in Rapidly Changing Environments - Probing Matter at the Extremes” to be held at ICTP in Trieste from 4 to 9 August 2014.
This Workshop will be focused on hydrodynamic instabilities and on interfacial and turbulent mixing in fluids, plasmas and materials under extreme conditions of high energy density and sharply changing flow fields, and on their applications in nature and technology, from atomistic to astrophysical scales.
The Workshop is a part of the program “Turbulent Mixing and Beyond” (TMB) that was developed in 2007 with the support of the ICTP and international funding agencies and institutions to bring together researchers from different areas of science, engineering and mathematics, and to focus their attention on the fundamental problem of non-equilibrium processes and turbulent mixing, http://www.ictp.it/~tmb.
Hydrodynamic instabilities and mixing control a broad variety of processes in fluids, plasmas and materials. These processes can be natural or artificial, their characteristic scales can be astrophysical or atomistic, and energy densities can be low or high. Examples include inertial confinement, heavy ion, and magnetic fusion, stellar and planetary convection, material transformation under impact, supersonic flows, and laser micromachining.
The tremendous success that has been recently achieved in large-scale numerical simulations, in laboratory experiments (especially those in high power laser systems), in technology development (including possibilities for improvements in precision, dynamic range, reproducibility, accuracy, and data acquisition rate), and in theoretical analysis (e.g., new approaches for handling multi-scale, non-local and statistically unsteady dynamics) renders unparalleled opportunities to explore the properties of mixing and to touch the matter at the extremes.
This success, as well as the striking similarity in behavior of hydrodynamic instabilities and mixing in the vastly different physical regimes, make this moment right for integrating our knowledge of the subject and for further enriching its development.
The TMB Workshop ‘Mixing in Rapidly Changing Environments’ will consist of key-note and invited lectures, contributed talks, poster presentations, and round table discussions. The results of the Workshop will be published.

Compact moduli of noncommutative algebraic varieties via quivers
Abstract:
(joint works with Tarig Abdelgadir and Kazushi Ueda). It is known that the category of coherent sheaves on certain varieties, such as projective spaces and del Pezzo surfaces, are derived equivalent to the category of representations of certain quivers with relations. When we allow the variety to deform, even into the noncommutative directions, the relations of the quiver also deform correspondingly (with the quiver unchanged). This allows us to construct `approximate' compactified moduli space of noncommutative deformations of such varieties as the moduli space of relations of the corresponding quiver. In this talk I will explain the generality of this construction and what we know so far in the case of del Pezzo surfaces.

Hurwitz numbers for real polynomials
Abstract:
We introduce a signed count of real polynomials which gives rise to a real analog of Hurwitz numbers in the case of polynomials. The invariants obtained allow one to show the abundance of real solutions in the corresponding enumerative problems: in many cases, the number of real solutions is asymptotically equivalent (in the logarithmic scale) to the number of complex solutions.
This is a joint work with Dimitri Zvonkine.

Joint ICTP-IAEA School of Nuclear Knowledge Management | (smr 2600)
The 10th edition of the School of Nuclear Knowledge Management (NKM School) is jointly organized by The Abdus Salam International Centre for Theoretical Physics (ICTP) and the International Atomic Energy Agency (IAEA). On top of recognizing a decade of successful cooperation between the IAEA the ICTP, 2014 will also mark ICTP’s 50th anniversary.
PURPOSE - The School is a certificate course aiming to provide specialized education and training on development and implementation of knowledge management programmes in nuclear science and technology organizations.
FOCUS - The School focuses on methodologies and practices, and explores various dimensions of NKM such as processes and tools, challenges and benefits, culture influence, relationship with human resource development, information technology for knowledge preservation and sharing, etc. Learning is supplemented with real life examples, good practices and lessons learned from NKM programmes in different types of nuclear organizations. The aim is to encourage ‘forward thinking’ and to make theory and insights directly applicable in the workplace.
TOPICS - The main topics of the School are:
• Nuclear Knowledge and Knowledge Management Fundamentals;
• Developing Policies and Strategies in Managing Nuclear Knowledge;
• Managing Nuclear Information Resources;
• Human Resources Development, Risk of Knowledge Loss and Knowledge Transfer;
• Practical Guidance and Best practices on NKM.
LOCATION - The School will be taking place in Trieste, Italy at the ICTP premises.
DURATION - 25th to 29th August 2014.
DELIVERY METHODS – The School starts before going to Trieste, with a pre-training done via e-learning. This pre-training introduces applicants to the fundamentals of NKM, and ensures a common understanding of the basics, allowing a more efficient and valuable interaction with peers and lecturers during the face-to-face in-class training that follows.
Once in ICTP, topics are introduced through presentations delivered by recognized experts, followed by case studies, practical and breakout sessions where the participants will have the opportunity to discuss issues and solutions. An NKM group project is also developed over the week.
WHO CAN PARTICIPATE - The invitation to the School is extended to young professionals from the nuclear field that have - or may in the near future have – a lead role in managing nuclear knowledge. Experts and scientists from countries that are members of the UN, UNESCO or IAEA may attend. Although the main purpose of the Centre is to help researchers from developing countries through a programme of training activities within a framework of international co-operation, a limited number of participants from developed countries are also welcome. Due to organizational reasons, the total number of participants is limited. The School will be conducted in English therefore participants must have adequate language knowledge.
SELECTION PROCEDURE - The selection procedure has two phases. The applicants are first screened based on their qualification, skills, abilities and experience. The pre-selected group will then undertake the online pre-training course (on an e-learning platform) and a test. The results from the test will be one of the final elements considered in the final selection of participations for the School.

Conference on Field Theory Methods in Low-Dimensional Strongly Correlated Quantum Systems | (smr 2601)
The Abdus Salam International Centre for Theoretical Physics, is organizing a Conference on Field Theory Methods in Low-Dimensional Strongly Correlated Quantum Systems to be held from 25 to 29 July 2014.
One and two dimensional strongly correlated quantum systems continue to be an exciting research area in both condensed matter and cold atom physics. Field theory methods are a key tool in many theoretical approaches to low dimensional systems. The conference will focus on the application of field theory methods to strongly correlated, low dimensional systems in solids (chains, ladders and quasi-2D materials) as well as in trapped, ultra- cold atoms. Key advances that have been achieved in recent years include the development of new methods to determine dynamical response functions, the experimental realization (combined with full, quantitative theoretical descriptions) of paradigmatic models of quantum phase transitions, confinement and dynamical cross-over, and the development of theoretical approaches that finally permit the description of effects due to spectral nonlinearity in one dimensional metals.
Topics covered by the conference include:
+ Nonlinear Luttinger Liquids
+ Dynamics quasi-1 D compounds
+ Impurities and disorder in quantum spin chains and cold atoms
+ Fluctuation-driven instabilities of correlated fermions
+ Dynamics of ultra-cold atomic gases
+ Integrable and near-integrable systems

A universal correction to higher spin entanglement entropy
Abstract. We consider conformal field theories in 1+1 dimensions with W-algebra symmetries, deformed by a chemical potential \mu for the spin-three current. We show that the order \mu2 correction to the Re'nyi and entanglement entropies of a single interval in the deformed theory, on the infinite spatial line and at finite temperature, is universal. The correction is completely determined by the operator product expansion of two spin-three currents, and by the expectation values of the stress tensor, its descendants and its composites, evaluated on the n-sheeted Riemann surface branched along the interval. This explains the recently found agreement of the order \mu2 correction across distinct free field CFTs and higher spin black hole solutions holographically dual to CFTs with W-symmetry.

Informal seminar on: "Nanoscience in Costa Rica and Computational study of Pakhomovskyite electronic and magnetic properties"
In this talk I'm going to present some of the experiments and projects that are currently active at the Universidad de Costa Rica in the area of nanoscience. In particular I'm going to mention some projects where the support of DFT and MD calculations will have a relevant impact in the interpretation and comprehension of present experimental results.
In the second part, I'm going to focus on a specific project: "Ca-Co phosphates as catalysts in water electrolysis". This project aims to study the catalytic properties of Pakhomovskyite.
Pakhomovskyite is a vivianite structure with layers of cobalt phosphate structures that are joined together by hydrogen bonds. This structure has been proposed for various cobalt based catalysts. The main advantage is that the structure can sustain changes in oxidation state while the same structure remains. The experimental results lead to important questions in water splitting catalysis. Nevertheless, none theoretical work has been done in this material. Therefore, in the present project we aim to use DFT calculations in order to study its magnetic and electronic properties, allowing us to select the best candidates to be synthesized later by the experimental group.

Extreme events such as cyclones, earthquakes, power blackouts or traffic jams are not uncommon.
Study of such events using the framework of extreme value theory has a long history. In this talk, we will introduce the idea of extreme events and review some of the recent results.
In the second half, we will discuss transport processes based on random walks and associated extreme events taking place on complex networks. We show that extreme events on complex networks are more likely to take place on small degree nodes and not on the hubs.
We will discuss some generalisations and applications of these results.

A characterization of a Kondo system using only entanglement measures is provided. For this purpose: I shall firstly analyze a spin realization of the single channel Kondo model and show how one can determine the Kondo screening length by a measure of entanglement. I then show how the entanglement with the impurity “stored” in the Kondo cloud may be used to generate distance independent long range entanglement between the end point of a Kondo spin chain.

Advanced Workshop on Interdisciplinary Views on Chromosome Structure and Function | (smr 2604)
The Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy, is organizing an
Advanced Workshop on "Interdisciplinary View in Chromosome Structure & Function", to be held
in Trieste, Italy, from 15 - 19 September 2014.
Understanding how the genetic material is organized in space in eukaryotes and bacteria is one of the big challenges of current molecular biology. It is now clear that the complexity of the cellular machinery is so profound that its full comprehension can be pursued only through the joint efforts of scientists coming from cross-related disciplines like molecular biology, systems biology, bioinformatics and physics. This Workshop aims at bringing scientists from these different disciplines in a real interdisciplinary context.
The state-of-the-art of experimental, modeling and physical aspects in chromosome organization will be discussed, with particular emphasis on future important challenges.
Topics include:
-High-throughput and imaging methods for chromosome structure and dynamics;
-Gene regulatory networks in eukaryotes and bacteria: experiments and modeling;
- Large-scale physical modeling and simulation of chromosome structure;
- System biology of gene expression and regulation.

Super-renormalizable & Finite Gravitational Theories
Abstract. We hereby introduce and extensively study a class of non-polynomial higher derivative theories of gravity that realize a ultraviolet (UV) completion of Einstein general relativity. These theories are unitary (ghost free) and at most only one-loop divergences survive. The outcome is a class of theories super-renormalizable in even dimension and finite in odd dimension. Moreover, we explicitly prove in D=4 that there exists an extension of the theory that is completely finite and all the beta functions vanish even at one-loop. These results can be easily extended in extra dimensions and it is likely that the higher dimensional theory can be made finite too. Therefore we have the possibility for "finite quantum gravity" in any dimension.

Joint ICTP-IAEA Workshop on Nuclear Reaction Data for Nuclear Power Applications | (smr 2605)
The Abdus Salam International Centre for Theoretical Physics (ICTP, Trieste, Italy) and the International Atomic Energy Agency (IAEA, Vienna, Austria) will jointly organize this Workshop to be held at the ICTP in Trieste from 22 to 26 September 2014. The Workshop will continue a long tradition of workshops on nuclear theory initiated in late sixties.
The Workshop represents a unique forum where nuclear scientists and engineers can get extensive and up-to-date information on the whole 'know-how' of nuclear data, from the physics of nuclear reactions to the production and validation of evaluated nuclear data files.
In the era of vanishing expertise and infrastructure due to low support for nuclear reactor activities, this type of training is important, particularly in view of challenges posed by emerging innovative fuel cycle concepts, enhanced safety requirements and radioactive waste incineration.
The purpose of the Workshop is to train scientists and engineers from both developing and developed countries in modern nuclear reaction theory, nuclear data production and validation, and data use, with particular emphasis on applications in nuclear reactor physics, design and safety. Participants will gain an overview of modern computer codes relevant to these topics. Furthermore, they will be introduced to the online retrieval of nuclear data.

Basic Notions Seminar "Impartial Games"
An impartial game is a game in which two players, taking turns, make a move allowed in the game, each having complete information and where no chance is involved. The allowed moves, in any given state in the game, are the same for both players. In normal play, a player unable to move looses.
In this talk I will discuss the remarkable fact that all impartial games are essentially the same.

Advanced Workshop on Landau-Zener Interferometry and Quantum Control in Condensed Matter | (smr 2677)
The ICTP - Eurasian Centre for Advanced Research (ICTP-ECAR), Center for NanoScience (CeNS, Munich, Germafly) and Nanosystems Initiative Munich (NIM, Munich, Germany) are organizing an Advanced Workshop on Landau - Zener Interferometry and Quantum Control in Condensed Matter, to be held in ICTP-CAR Centre, IZTECH, Izmir (Turkey), from 29th September to 3rd October 2014.
The workshop will address recent developments on Landau-Zener dynamics and related quantum control in complex systems including (but not limited to) many-body effects in ultracold gases, dissipative Landau-Zener transitions, Landau-Zener interferometry in superconducting qubits, double and triple quantum dots. 'spin & charge qubits, N-V centers and nano-mechanical systems.
The centra1 idea of this workshop is to bring together various condensed matter communities, dealing with comRlex systems, where the nonequilibrium dynamics at avoided crossings is (other than in pure atomic systems) highly influenced by many-body interactions and, in many cases, environmental fluctuations.
We expect about 100 participants including about 25 invited presentations given by the world experts in order to exchange ideas and shape new links beyond the traditional community boundaries. We hope to facilitate Landau-Zener interferometry and quantum control as one of the key ectroscopic tools in condensed matter systems for the future.

Joint ICTP/SISSA Statistical Physics Seminar: "Low energy electron-phonon effective action from symmetry analysis"
In this talk, based on a detailed symmetry analysis, I will state the general rules to build up the effective low energy field theory describing a system of electrons weakly interacting with the lattice degrees of freedom. The basic elements in the construction are the invariant tensors that keep track of the microscopic discrete symmetries into the coarse-grained action. The approach can be applied to lattice systems in arbitrary dimensions and in a systematic way to any desired order in derivatives. I will show the application of the method to the honeycomb lattice and re-obtain the well-known effective action for graphene, containing Dirac fermions coupled to a fictitious gauge field. The talk is based on the results of arXiv:1303.3442

Towards a bifurcation theory of random dynamical systems
Abstract:
A bifurcation theory for random dynamical systems (ie dynamical systems with noise) is still only in its infancy. We discuss several recent developments on the basis of the very simple example of a pitchfork bifurcation in the presence of so-called additive noise. My presentation will touch upon recent joint work with Mark Callaway, Martin Rasmussen, Doan Thai Son and Christian Rodrigues.

Advanced School on Megathrust Earthquakes and Tsunami | (smr 2609)
The Abdus Salam International Centre for Theoretical Physics, will organize an
Advanced Workshop on Megathrust Earthquakes and Tsunami from 12 to 25 October 2014. It will be directed by R. Madariaga (Ecole Normale Superieure, France) and A. Aoudia (ESP, ICTP, Italy).
Seismicity at subduction megathrusts is responsible for most of the seismic energy globally released during the last century. Studies of recent giant megathrust earthquakes suggest new outstanding issues and unexpected processes and characteristics regarding the genesis of these events and of the related tsunami waves. These events have re-opened the discussion about which kind of subduction zones are prone to have very large and tsunamigenic events. These subduction zones have been classified in the past following criteria that have been put into question by several recent events. A new view of seismic hazard in subduction zones is emerging that could be of interest to many earthquake scientists in both developing and developed countries.
We propose an advanced workshop and school where the above listed issues and related subjects will be discussed from a fundamental point of view and also with applications in specific subduction zones worldwide.
TOPICS:
The programme will involve a series of lectures, semmars, discussions and practical exercises in the following topics:
- Seismology of megathrust earthquakes
- Geodesy and remote sensing of megathrust earthquakes
- Paleoseismology of megathrust subduction zones
- Tsunami physics and geology
- Petrological and geological models of megathrust subduction zones
- Mechanical models of megathrust subduction zones
- Rapid detection and characterization of megathrut earthquakes

Leptogenesis at LHCb, BELLE II and SHiP
Abstract. We show that existing laboratory experiments have the potential to unveil the origin of matter by probing leptogenesis in the type-I seesaw model with three right handed neutrinos and Majorana masses in the GeV range. The baryon asymmetry is generated by CP-violating flavour oscillations during the production of the right-handed neutrinos. In contrast to the case with only two right handed neutrinos, no degeneracy in the Majorana masses is required. The right-handed neutrinos can be found in meson decays at BELLE II, LHCb or the proposed SHiP experiment.

4th International Workshop CHArMEx - the Chemistry-Aerosol Mediterranean Experiment | (smr 2610)
ChArMEx is part of the international and interdisciplinary metaprogramme MISTRALS (Mediterranean Integrated STudies at Regional and Local Scales). Its aim is to assess the present and future state of the atmospheric environment in the Mediterranean Basin, and its impacts on the regional climate, air quality and marine biogeochemistry, in a context of strong regional anthropogenic and climatic pressures. This region shows high level of ozone and aerosol during summertime. It is a receptor area of long-range transport of atmospheric pollution. It is also considered a hot-spot of climate change, with significant projected summertime warming and precipitation decrease that have the potential to further enhance atmospheric pollutants and natural aerosol concentrations. The Workshop will focus on different approaches to study Mediterranean atmospheric chemistry and climate such as satellite observations, airborne and ground measurements, and modelling. Recent results of the ChArMEx experiment will also be discussed. It is intended to promote scientific exchanges and collaborations between participants. As such it is open to scientists and students interested in atmospheric chemistry, aerosols and climate-chemistry interactions in the Mediterranean region climate. Talks from participants are welcome, and a Poster Session will also be included in the programme. ICTP encourages applicants to submit a short one-page abstract along with their online application form.

Seminar in QUANTITATIVE LIFE SCIENCES: "From worm burrows to dinosaur footprints: An ichnological journey into biological behavior"
Since Paleolithic times, humans have tried to read biological behavior through animal and plant traces. Over the centuries, this art of survival has evolved into a discipline halfway between Earth Sciences and Life Sciences: Ichnology.
This seminar discusses the fundamentals of the study of traces, presenting robust techniques to decipher the ichnological alphabet – from worm burrows to dinosaur footprints. Special attention will be paid to the application of quantitative techniques such as fractal geometry, network theory and artificial life. Fossil and modern environments will be explored, underlining the (paleo)biological significance of 600 millions of years of bioturbation in marine and terrestrial ecosystems. In fact, burrows, footprints, borings, coprolites are fossil behavior and, as such, they are a valuable tool in sedimentary geology, evolutionary biology and paleontology.

Workshop on Probing and Understanding Exotic Superconductors and Superfluids | (smr 2612)
This Workshop is meant to showcase several new approaches to the experimental and theoretical understanding of superconductors and superfluids, comparing solid-state and ultracold-atoms advances with the aim of a cross-fertilization between the two fields. It will feature topics that are rapidly developing, ranging from novel (time-resolved and k-resolved) optical spectroscopies to new trapping and imaging methods for ultracold gases, with the unifying contribution of different theoretical approaches, such as Dynamical Mean-Field theory, Diagrammatic and Quantum Monte Carlo methods. Special attention will be devoted to the exotic superfluid and superconducting states which arise from the interplay between pairing, correlations, disorder and reduced dimensionality.

Joint ICTP-IAEA Conference on Models and Data for Plasma-Material Interaction in Fusion Devices | (smr 2614)
Introduction: Plasma-wall interaction in fusion devices encompasses a wide variety of processes. On a short timescale these include deposition of energetic plasma particles (primarily hydrogen and helium) into the surface, physical and chemical sputtering of surface material into the plasma, and reflection and desorption of particles from the surface. On a longer timescale the processes include diffusion of hydrogen and helium in the wall and changes in surface composition, morphology and material microstructure due to plasma bombardment and (in a reactor) neutron irradiation. Together these processes are extremely important in determining the plasma performance, the lifetime of plasma-facing components, trapping and retention of the tritium fusion fuel in the wall, and ultimately the feasibility of fusion power production. The gap between what is known about plasma-material interaction and what is needed to design a fusion reactor is most severe for the effects of radiation damage on hydrogen retention properties of plasma-facing materials. Computations are particularly important for this problem, because experiments cannot fully simulate the radiation conditions in a fusion device. Appropriate computational materials tools range from statistical or otherwise averaged (binary collision approximation, kinetic Monte Carlo) and mechanical (molecular dynamics) models to semiempirical (tight binding) density functional theory codes and first principles quantum mechanical codes for inhomogeneous materials. Any of these codes has its own needs for fundamental data, which are in many cases obtained by parameterization of results of other calculations.
Purpose: The conference is intended to bring together researchers from the areas of fusion energy science and materials science in order to review advances in computational studies of plasma-material interaction processes and the evolution of material microstructure in fusion devices. Within this area the programme will emphasize work that is relevant to hydrogen (tritium) trapping and transport in candidate fusion reactor wall materials. This includes modelling of the effects of irradiation upon material microstructure and modelling to understand the influence of microstructure on hydrogen trapping and transport. Participants with a background in plasma-wall interaction in fusion experiments should return from the conference with a richer understanding of the wide range of computational methods that are used for development of plasma-material interaction data and material properties data for fusion plasma and fusion materials modelling. Participants from the area of materials science should obtain guidance about new work that is most needed to improve understanding of plasma-material interaction processes and material damage processes that are relevant for fusion energy development. The conference format is meant to encourage new collaborations on computational studies of plasma-material interaction in fusion devices.
Topics: The conference programme will emphasize uses of the more fundamental computational tools (based on quantum mechanics) and parameterization of results from such tools in the form of interaction potentials and transition rates for applied studies. Specific topics include the following.
* Direct uses of ab initio and semi-empirical quantum mechanical codes for study of materials microstructure, trapping and transport of hydrogen and helium in fusion wall materials.
* Optimization of parameters in semi-empirical codes and parameterization of results of quantum mechanical calculations in the form of interaction potentials and transition rates for classical models.
* Molecular Dynamics, Binary Collision Approximation and Kinetic Monte Carlo studies of plasma-material interaction, radiation damage processes and material and surface evolution.
* Multi-method and multi-scale simulations; acceleration approaches.
* Uncertainty estimation and uncertainty propagation from quantum mechanical calculations through interaction potentials to outputs of longer time-scale calculations.
* Parameterization of material microstructure and its effect on mobility and trapping of hydrogen and helium in fusion wall materials.
* Simulation and interpretation of diagnostics of material microstructure, radiation damage, hydrogen and helium in fusion materials and plasma-material interaction Participants will be active researchers in the subject area of the conference and we expect a scientific contribution (talk or poster) from each participant.

Joint ICTP/SISSA Statistical Physics seminar: Inverse problems for spreading dynamics on networks.
Who are the most influential players in a social network? What's the origin of an epidemic outbreak? The answer to simple questions like these can hide incredibly difficult computational problems, that require powerful methods for the inference, optimization, and control of dynamical processes on large networks.
I will present a statistical mechanics approach to inverse dynamical problems in the idealized framework provided by simple models of irreversible contagion and diffusion on networks (linear threshold model, susceptible-infected-removed epidemic model). Using the cavity method (belief propagation), it is possible to explore the large-deviation properties of the dynamics and develop efficient message-passing algorithms to solve optimization and inference problems even on large networks.

First Workshop on Climate Change, Variability and Modeling over Central America and Mexico | (smr 2637)
Mexico and Central America are vulnerable regions to extreme climatic events that causes socio-economical and natural disasters. Central America is a hot spot for climate change impact (Giorgi, 2006), being one of the most vulnerable regions in the world to climate change. Recent simulations performed with RegCM, contributing to the Coordinated Regional climate Downscaling Experiment (CORDEX) over Central America have shown that the use of regional climate models allows for a better representation of the local climate features and meso-scale phenomena, such as for
example tropical cyclones compared with coarser resolution Global Models. Therefore, the main purpose of the workshop will be to provide extensive sessions focused on the implementation of techniques to carry out analysis of climate variability and climatic change in this area. The use of the regional climate model RegCM4 model will be shown as a tool to study climate-related phenomena at high resolution.
This workshop will be organized with lectures and lab sessions which intend to provide a background on climate studies focused over Central America and Mexico, addressing issues like theory of regionaI climate dynamics and climatic change.
One aim of the workshop is to start a community of users of Regional Climate Modeler focused over Mexico and Central America inline with the CORDEX framework. A limited number of participants is envisioned, with proven experience in handling climate data, and that have interest in starting to use the RegCM4 as a tool for regional climate studies.

Joint ICTP/SISSA Statistical Physics seminar: "Eigenstate thermalization hypothesis (ETH) and integrability in quantum spin chains"
ABSTRACT
We investigate the eigenstate thermalization hypothesis (ETH) in integrable models, focusing on the spin-1/2 isotropic Heisenberg (XXX) chain. We verify that ETH holds for typical eigenstates (weak ETH scenario). Specifically, using a numerical implementation of state-of-the-art Bethe ansatz results, we study the finite-size scaling of the eigenstate-to-eigenstate fluctuations of the reduced density matrix. Fluctuations are normally distributed, and their standard deviation decays in the thermodynamic limit as L^{-1/2}, with L the size of the chain. This is in contrast with the exponential decay that is found in generic non-integrable systems. Finally, we investigate the entanglement properties of the excited states of the XXX chain. We numerically verify that typical mid-spectrum eigenstates exhibit extensive entanglement entropy (i.e., volume-law scaling).

Switching limits in geometric representation theory
Abstract: Atiyah and Bott famously showed that Borel-Weil-Bott and the equivariant localization theorem for the flag manifold imply a proof of the Weyl-Character formula. I'll explain how generalizing this in a certain way to some infinite dimensional Kac-Moody requires that certain limits be switched for some infinite-dimensional varieties, together with an idea of Graeme Segal, and give some new sufficient conditions for when this may be done. This all sounds a bit technical, but I really won't assume very much.

ICTP-NCP School on LHC Physics | (smr 2632)
The Abdus Salam International Centre for Theoretical Physics (ICTP) is organizing, in collaboration with the Pakistani National Centre for Physics (NCP), a School on LHC Physics to be held in Islamabad, Pakistan from 25 August to 5 September 2014.
INTRODUCTION
The Large Hadron Collider (LHC) is the largest particle accelerator ever built in the history in terms of energy and luminosity. LHC is currently under operation at European Organization for Nuclear Physics (CERN), Geneva. The discovery of the Higgs Boson was announced by two big LHC experiments called CMS and ATLAS on July 4, 2012.
PURPOSE The purpose of this School is to introduce young researchers in particular graduate students how to analyze the data from LHC. Several countries in the region are working on LHC such as: China, India, Iran, Malaysia, Turkey and Pakistan. This particular School is organized in the same spirit as the CMS Data Analysis Schools (CMSDAS) organized on regular basis by CERN and Fermilab. The School will serve the purpose of regional school.
TOPICS
The real goal of the School is “from raw data to physics publication”. During the School we plan to cover the following areas:
•Standard Model and Beyond
•Higgs Searches and Searches for Exotic Particles
•Detector Physics
•Event Generator
•Analysis tools for LHC data
Supplementary lectures related to various programming tools needed to analyze LHC data will cover
•Operating System (Linux)/Programming Languages (C++, Python, Perl)
•Root/Event Generator – Pythia
•CMSSW •Data Access using Grid
•Statistical Techniques and Fitting data using Roofit FORMAT
The two-week school will consist of morning sessions devoted to inspirational plenary talks combined with the execution of a series of so-called "short" and "long exercises" that will represent the main goal of the School. The first part of the School will be devoted to "short exercises" (several hours duration) to cover all of the objects from jets to muons, as well as various techniques from event generators to setting upper limits. During a 2.5 days intensive session, focused teams of about 6-8 students each, will perform "long exercises", i. e. detailed physics measurements using LHC data. Both short and long exercises will be designed and facilitated by teams of 2-3 experts. Some long exercises go beyond the current state of the art of the corresponding CMS analysis
PARTICIPATION Scientists and students from all countries that are members of the United Nations, UNESCO or IAEA, may attend the School, however, since this is a regional activity, priority will be given to graduate researchers and research scientists from the region.
As the School will be conducted in English, participants should have an adequate working knowledge of that language. Although the main purpose of the Centre is to help research workers from developing countries through a programme of training activities within a framework of international cooperation, a limited number of students from developed countries are also welcome to attend. As a rule travel and subsistence expenses for participants should be borne by their home Institutions. Every effort should be made by candidates to secure support for their fare (or at least half fare). However, limited funds are available for some participants who are nationals of, and working in, a developing country, and who are not more than 45 years old. Such support is available only for those attending the entire activity. There is no registration fee.

The prospect of a continuing world-wide use of nuclear technology -for the generation of electricity and other energy services and in a diversity of nuclear applications in medicine, agriculture, and industry, as well as the ageing cadres in the field - points to the need for new and greatly expanded global cadre of nuclear professionals. A highly competent management is vital to the success at all stages of development or re-launching of a nuclear programme.
This school will focus mainly on training young professionals from developing and developed countries with managerial potential on aspects of the industry that will ensure their broad understanding of the current issues that need to be tackled in their various countries.
During this training programme, the participants will gain awareness of the most recent developments in nuclear energy and the IAEA specific knowledge and broad international perspective on issues related to the peaceful use of nuclear technology. The School will consist of a series of keynote presentations by leading IAEA specialists on topics relevant to managing nuclear energy programs followed by practical sessions discussing the issues raised and difficulties envisaged. All chosen participants will be expected to be actively involved in discussions, assigned projects, panel reviews and all school activities.
The following topics will be covered:
• World Energy Balance, Geopolitics and Climate Issues;
• Energy Planning, Energy Economics and Nuclear Power Economics and Finance;
• Nuclear Power- Technology and Life Cycle;

Joint ICTP-IAEA School on Novel Experimental Methodologies for Synchrotron Radiation Applications in Nano-science and Environmental Monitoring | (smr 2611)
SCHOOL PURPOSES AND TOPICS: The purpose of the Synchrotron Radiation School is to introduce and demonstrate advanced analytical methodologies based on X-ray spectrometry with application in the fields of Nano-Science and Environmental monitoring. The introduction of environment-friendly energy sources and the diagnosis, monitoring and understanding of environmental problems are issues of high concern for developing countries due to the destructive impact of the growing industrialization. These problems in many cases can be tackled by novel technologies based on the development of nano-structured materials that can be fully characterized due to the remarkable properties of synchrotron radiation. This two-week School is addressed to young motivated scientists with a Ph.D., or at least several years of research activity. It will offer a balanced program composed by lectures, tutorials and practical hands-on training sessions at different Elettra beamlines including the newly developed XRF beamline and the IAEA multipurpose endstation. The School aims to enhance the skills of participants in applying synchrotron radiation based on X-ray spectrometry techniques. It will also represent an opportunity for young researchers from developing countries to utilize in a competitive manner the access mechanisms offered by Elettra, the IAEA and the ICTP.
The following specific topics will be included:
•Synchrotron Radiation Instrumentation: X-ray optics, UHV instrumentation, Advanced sample manipulator systems, trends and developments
•Theory and analytical applications of X-ray Absorption Fine Structure (XAFS) techniques
•Synchrotron Radiation based X-Ray Fluorescence (XRF) analysis Methodologies: Grazing Incidence XRF (GI-XRF), Total Reflection XRF (TR-XRF), 2D-3D Micro-XRF analysis, Quantification methodology and Monte Carlo Methods
•Tutorials on XRF/GIXRF and XAFS data analysis and on Monte Carlo Methods
•Experimental hands on sessions at Elettra XRF, TwinMic and XAFS beamlines

Monopole correlations in holographically flavored liquids
Abstract. Given a many-body system in (2+1) dimensions with a conserved U(1) current, an interesting probe of the IR dynamics is provided by weakly gauging the current and then studying the correlation functions of magnetic monopole operators in the resulting dynamical gauge theory. This correlation function is a non-perturbative object and so is somewhat difficult to calculate using conventional techniques. We review the expected behavior of such monopole correlations in different field-theoretical states. We then turn to holography and study monopole correlations in holographic liquids with fundamental flavor, where the monopole operator is dual to a bulk particle that carries magnetic charge, permitting a simple geometric understanding. We display consistency with expected field-theoretical results. For a charge-gapped phase this requires a discussion of monopole condensation in the bulk, which turns out to be equivalent to the capping off of the bulk flavor brane. In a compressible finite-density phase we present a novel calculation of the monopole correlation in space and time.

Spectral Properties of Group Algebra Elements
Abstract:
We are principally interested on determinant calculation and on eigenvalues with multiplicities determination of the regular representation of group algebra element. We first briefly review the representation of group algebra and its connection with arrangements of hyperplanes. After that, we expose the determinant calculations of elements of the group algebra of the symmetric group and of the hyperoctahedral group. We also expose the eigenvalues with multiplicities determination of an element of the group algebra of the symmetric group. Then, we finish with the presentation of an open problem which is the eigenvalues with multiplicities determination of an element of the group algebra of the hyperoctahedral group.

Big Bang Synthesis of Nuclear Dark Matter
Abstract. I will discuss the physics of dark matter models featuring composite bound states carrying a large conserved dark "nucleon" number. The properties of sufficiently large dark nuclei may obey simple scaling laws, and we find that this scaling can determine the number distribution of nuclei resulting from Big Bang Dark Nucleosynthesis. For plausible models of asymmetric dark matter, dark nuclei of large nucleon number, e.g. > 10^8, are synthesised, with the number distribution taking one of two characteristic forms, independent of many details of the initial conditions and small-number interactions. I will also briefly discuss the constraints arising from the novel dark sector energetics, possible modifications to astrophysical processes, and the potential direct detection signals.

Joint ICTP-IAEA Meeting on Training in Patient Safety in Radiotherapy | (smr 2593)
The aim of this course is to provide advanced knowledge to meet the increasing need of radiation protection and safety of patients undergoing radiotherapy procedures.
The course will:
- disseminate information on lessons learned from radiotherapy incidents and accidents that have occurred in the past
- train participants in the critical aspects of radiotherapy safety learning and implementation
- train participants in methods for retrospective and prospective risk analysis in radiotherapy
Radiotherapy has long been an effective way of treating cancer and it is estimated that 50-60% of patients with cancer would benefit from radiotherapy. Expanding radiotherapy into areas with limited current access has the potential to save a great number of lives, but it is mandatory that the expansion is done with safety in mind, considering the complexity of this high-technology treatment modality and the potential for serious consequences when something goes wrong. It is worth considering that there have been more deaths and early acute health effects due to radiation accidents in medical uses than due to any other source, including accidents at nuclear facilities.
While there is a broad agreement by experts that radiotherapy is a very safe form of treatment, where more than 5 million treatments are delivered annually in the world, there is also recognition that safety measures need to be further progressed at several levels for this complex and rapidly developing medical specialty. The need to develop leadership in radiation safety in radiotherapy is acute.
ICTP is a world renowned centre for training in physics and allied sciences and IAEA has developed lead in medical radiation protection. A program under the umbrella of both these organizations is expected to attract right talent and has potential to meet objectives of both organizations effectively.

Seminar in QUANTITATIVE LIFE SCIENCES: "Irreversibility and dissipation in multiple-scale systems"
Systems with disparate timescales are ubiquitous in physics and biology. Efficient modeling dictates to restrict the description to the slower processes and not to fully resolve the faster ones.
The seminar will discuss this general issue in stochastic systems with multiple timescales. In particular, the presentation will address the behavior of thermodynamics upon changing the level of resolution.
Stefano Bo will show how for non-equilibrium systems, under quite general conditions, properties of
the fast dynamics still affect thermodynamics on the slower scales therefore compromising
a description of the full system in terms of slow variables only.
Finally, two relevant examples will be given concerning Brownian motion and a simple
biochemical network.

Joint ICTP/SISSA Statistical Physics seminar: "Viscoelastic Interfaces Driven in Disordered Media & Applications to Friction"
Abstract:
Many complex systems respond to a continuous input of energy by an accumulation of stress over time, interrupted by sudden energy releases called avalanches. Recently, it has been pointed out that several basic features of avalanche dynamics are induced at the microscopic level by relaxation processes, which are neglected by most models. We have studied a minimal modification of a well-known model of avalanche dynamics, in which we take into account the presence of "relaxation processes". Precisely, we study a viscoelastic interface driven in a disordered medium.
In mean-field, we prove that our model interface has a periodic behavior (with a new, emerging time scale), with avalanche events that span the whole system. We compute semi-analytically the friction force acting on this surface, and find that it is compatible with classical friction experiments.
In finite dimensions (2D), the mean-field system-sized events become local, and numerical simulations give qualitative and quantitative results in good agreement with several important features of real earthquakes.

Winter School in Quantitative Systems Biology | (smr 2618)
The Abdus Salam International Centre for Theoretical Physics, is organizing a Winter School on Quantitative Systems Biology from 1 to 12 December 2014. It will be directed by V. Balasubramanian (Univ. of Pennsylvania, USA and CUNY Graduate Center, USA) and A. Treves (SISSA, Italy).
The School is part of the Programme in Biology between ICTP and the International Centre for Theoretical Sciences (ICTS) in Bangalore, India. New experimental techniques are opening windows on biological mechanisms inside the cell and in the brain, making these systems accessible to quantitative investigation. These advances have shown the importance of the concerted interaction of many agents in producing overall behaviors, and call for an understanding of biological functions at the systemic level. The series of Winter Schools in Quantitative Systems Biology, initiated in 2012, responds to the need to provide physicists with a broad exposure to quantitative problems in the study of living systems. The school is particularly targeted to young researchers, especially at the Ph.D and postdoc level who either work in this area or hope to do so.
The 2014 School will focus on Systems Neuroscience and cover different aspects of this rapidly developing field, such as:
• Neural coding and dynamics
• Connectomics
• Statistical inference in large neural datasets
• Optogenetics and gene expression in the brain
• Sensory systems: vision, olfaction, audition
• Computational neuroscience
• Synaptic plasticity, learning and memory
• Neuroscience of reward and decision making
• Spatial cognition
• Higher order cognitive processes
Series of lectures in these topics will be given by an array of distinguished speakers. Research seminars associated with the school will also provide a venue for scientific exchange at the cutting edge.

Latin American Conference and FPGA School on Advanced Instrumentation | (smr 2641)
The Abdus Salam International Centre for Theoretical Physics (ICTP, Italy) and the Costa Rica Institute of Technology (TEC, Costa Rica) will jointly organize a Latin-American FPGA School on Advanced Instrumentation, to be held in Santa Clara, Costa Rica, from 1 to 19 December 2014. The last three days of the school will be dedicated to the first regional Conference on Advanced Instrumentation (CRIA 2014) to be also held at Costa Rica TEC from 17 to 19 December 2014. Specific information about the Conference can be found a at http://cria2014.instrumentacionavanzada.net/
PURPOSE OF THE SCHOOL
The aim of school is to introduce physicists, engineers, computer scientists and other scientists to FPGA design methodologies focusing applications in scientific instrumentation. The school will represent a unique opportunity for many of the participants to gain skills for designing and developing complete high performance systems for scientific applications at low cost. Since the main barrier to exploit this technology is knowledge, this school will contribute to generate know how through hands-on experimental activities with state of the art hardware and software. The participants will count on international highly qualified lecturers and laboratory assistants who are selected professionals from academy, research centers and industry. This will contribute to provide a balanced perception and deeper understanding about limitations, trends and potentialities of this key technology. The School will contain about 35 hours of lectures and 35 hours of tutorials and assisted hands on laboratory sessions. During the last three days of the school, the selected applicants will also participate to the first regional conference on advanced instrumentation (CRIA 2014). It is expected to enhance the capabilities of researchers, teachers, and engineers in exploiting cost-effective programmable logic devices for their instrumentation needs and R&D for scientific and academic purposes. By promoting networking and open international collaborations and by stimulating a community of experimental scientists with the necessary skills and willingness to contribute to collaborative open hardware/software research projects, this school will contribute to alleviate the lack of stimuli and isolation that typically afflicts many professionals from developing countries.

An ordered anarchy from 5-dimensional S0(10)
Abstract: A mechanism to generate flavour hierarchy via 5-dimensional wave-function localization is revisited in the context of an SO(10) grand unified theory. An extra-dimension compactified on an orbifold generates different zero-mode profiles for fermions of different charges. Utilizing suitable scalar fields, a predictive model for fermion masses and mixing is constructed and shown to be viable with the current data. All the Yukawa couplings in the model are of order unity while the hierarchies among different fermions result from the wave-function profiles. The naturalness of anarchical Yukawa couplings and predictions for various observables in the lepton sector will be discussed.

TOPICS AND FACULTY
Teresa Krick (Universidad de Buenos Aires)
Arithmetic Nullstellensätze and Applications
The purpose of these lectures is to introduce Hilbert's Nullstellensatz, a cornerstone in Algebraic Geometry, and comment on its effective aspects, including degree and height aspects when the defining field admits a notion of height. We will introduce the ingredients used to obtain sharp estimates, which
can be useful on their own, and present some applications (by others) to problems on finite fields.
Christophe Ritzenthaler (Université Rennes 1)
Elliptic Curves and its Applications to Cryptography
The course will be a brief introduction to elliptic curves and its applications to cryptography and is divided into 4 lectures:
- definition(s) of an elliptic curve, group law, isomorphisms, torsion points, Weil pairing.
- elliptic curves over finite fields: two proofs of Hasse-Weil bound.
- elliptic curves over finite fields: how to count points? Overview of the different methods.
- application to cryptography: protocols, attacks and zoology of the existing models.
Peter Stevenhagen (Universiteit Leiden)
Algebraic Number Theory
- roots of the topic: Fermat, Euler, quadratic reciprocity.
- algorithmic requirements for the theory, e.g. in view of the number field sieve.
- working in number rings: integrality, (explicit) ideal factorization
- geometry of numbers, finiteness theorems (class group, Dirichlet unit theorem).
- Dedekind zeta function, computing fundamental number field invariants,
- local-global aspects: local fields, adeles, ideles.
- number field sieve.

An introduction to cohomology
(Basic Notions Seminar)
Abstract:
Although at first the standard definitions of cohomology may seem very strange, I will show how cochain complexes and cohomology arise naturally from the seemingly-trivial study of locally constant functions on smooth manifolds. As applications, we will see that a manifold cannot retract to its boundary, and that there is no orientation-reversing diffeomorphism of CP^2.

Toric hypersurface fibrations for F-theory and their Higgs branches
Abstract: We consider genus one fibrations for F-theory, with their fibers realized as hypersurfaces in the toric varieties associated to the 16 reflexive 2D polyhedra. For all of these we determine the gauge groups, matter representations, 6D matter multiplicities and 4D Yukawa couplings of their corresponding effective theories in a base independent way. We also explore the network of Higgsings relating these theories. Geometrically, such Higgsings correspond to extremal transitions induced by blow-ups in the 2D toric varieties. We recover the 6D effective theories of all 16 toric hypersurface fibrations upon successive Higgsings from the thee theories that exhibit Mordell-Weil torsion. We find that the three Calabi-Yau manifolds without section, whose fibers are given by the toric hypersurfaces in P^2, P^1x P^1 and the recently studied P^2(1,1,2), yield F-theory realizations of SUGRA theories with discrete gauge groups Z_3, Z_2 and Z_4. In these three manifolds, we also find codimension two I_2-fibers supporting matter charged only under these discrete gauge groups. This opens up a whole new arena for model building with discrete global symmetries in F-theory.
