Europe/Rome Understanding virulence remains a central problem in human health, pest control, disease ecology and evolutionary biology. Bacterial virulence is typically quantified by phenomenological indicators such as the LT50 (i.e. the time taken to kill 50% of an infected population). However, virulence emerges as a result of complex processes that occur at different stages: the pathogen needs to breach the primary host defenses, find a suitable environment to replicate, and finally express the virulence factors that cause lethality. It is well-known that pathogens exhibit a very broad spectrum of strategies to accomplish these three tasks, yet, phenomenological indicators such as the LT50 cannot distinguish the ability of the pathogen to invade the host from its ability to kill the host. Here, we propose a physical host-pathogen theory that shows how to disentangle colonization, growth, and pathogen lethality from the survival kinetics of a host population. Experimental data from Caenorhabditis elegans nematodes exposed to various human pathogens shows that host mortality becomes severe only once the pathogen population has reached its carrying capacity within the host. In the talk, I will present our theory and compare predictions against experimental data. ICTP ICTP pio@ictp.it

Europe/Rome Strongly correlated quantum systems exhibit a wide range of phases with unconventional behavior. These phases are characterized by non-trivial global entanglement patterns and cannot be described within the Landau paradigm due to their lack of local order parameters. In my talk, I will discuss how quantum information theory allows us to describe such systems in a way which reconciles their global entanglement with a local description, based on the framework of tensor networks. I will show how tensor networks allow to capture both the structure of the physical interactions as well as global topological entanglement within a unified local description, and how this allows us to build a comprehensive framework to study topologically ordered systems and their excitations. I will then discuss applications of this framework: First, I will show how it allows to characterize the precise nature of topological spin liquids; and second, I will discuss how it can be used to explain topological phase transitions driven by anyon condensation through phases in their entanglement, allowing us to devise measurable order parameters for anyon condensation and thus to study topological phase transitions at a microscopic level.

Europe/Rome The laws of thermodynamics can be extended to the nanoscale, where fluxes are fluctuating quantities. Little is known about extreme-value statistics of thermodynamic fluxes characterising the most extreme deviations from the average behaviours. Using Martingale theory, we study statistics of the negative records of stochastic entropy production in nonequilibrium steady states, and derive universal inequalities for such distributions of records. Furthermore, we explore the implications of our results in two non-equilibrium nanoscopic systems: single-electron transistors and molecular motors. We report on the experimental measurement of stochastic entropy production and of records of negative entropy in a metallic double dot under a constant external DC bias. Experimental results on the double dot confirm our theory and reveal a novel bound for the maximal heat that a mesoscopic system can absorb from its environment. We also explore our results in active biological processes and find predictions for the maximal excursion of a molecular motor against the direction of an external force. ICTP ICTP pio@ictp.it

Europe/Rome The main objective of the Forum is to bring together the main partners for realising international laboratories in South East Europe combining capacity building with bringing nations together following the CERN model. Among them are designers of the projects, potential future users of the region, scientists and engineers from universities and national laboratories, representatives of industry, and of government agencies. In introductory presentations the importance of international cooperation for science and training in the region will be illuminated. Two large projects from which the region could benefit particularly will be presented. Their concepts have been worked out by two groups of international experts and they are based on most modern technological developments enabling cutting-edge research in many domains relevant to society. One is a synchrotron light source providing radiation research possibilities in many domains from physics to biology, material science, environmental science and even archaeology and medicine. The users' community would come mainly from university faculties and also industry. The second project is a facility for cancer research and treatment with heavy particles (protons and carbon nuclei) which would also enable biomolecular research including experiments with small animals. For both facilities a number of options will be presented and it is hoped that the discussions will provide indications which choices would be most interesting for the region. Training of scientists, engineers and technicians is considered to be important from the beginning. Since the realisation of these projects will require several years this time will be extensively used to train experts in order to build-up expertise, i.e. to form a sufficient critical mass of staff members for operation of the machines as well as to create users' communities. Thus these opportunities will be mainly for the benefit of the young generation although they will also serve to reverse the brain drain. Since the general know-how and technology transfer will be of particular interest for the region several presentations will consider how this can be achieved in the most efficient way. Two special activities instigated by the projects may trigger developments for the whole region. This would be the development of powerful digital networks and large data handling necessary to transfer data from the central laboratory to the users. Setting up of such a network for oncologists might be of particular interest. Another activity reaching beyond the particular projects considered would be the installation of solar power panels to reduce the operating cost for electricity of the facilities, boosting the general development of alternative energy production in the region. GRANTS: a limited number of grants are available to support the attendance of selected participants, with priority given to participants from the South East Europe. There is no registration fee. Requests for contributions to the session "Short presentations of interest to participate in IIST (International Institute for Sustainable Technologies)", on 26 January morning, are invited to be made in the online form (comment section) indicating also the title of the contribution.

Europe/Rome A new algorithm to solve the TDDFT equations in the space of the density fitting auxiliary basis set has been developed and implemented in ADF.1 The TDDFT equations are recast to a non-homogeneous linear system, whose size is much smaller than in Casida formulation, allowing to calculate a wide portion of the absorption spectrum for large systems. The method extracts the spectrum from the imaginary part of the polarizability at any given photon energy, avoiding the bottleneck of Davidson diagonalization. The original idea which made the present scheme very efficient consists in the simplification of the double sum over occupied-virtual pairs in the definition of the dielectric susceptibility, which allows an easy calculation of such matrix as a linear combination of constant matrices with photon energy dependent coefficients. The method has been applied to very different systems in nature and size (from H2 to [Au309]-)2,3. In all cases, the maximum deviations found for the excitation energies with respect to Casida approach are below 0.2 eV. The new algorithm has the merit to calculate the spectrum at whichever photon energy but also to allow a deep analysis of the results, in terms of Transition Contribution Maps,4 plasmon scaling factor analysis5, induced density analysis, and with a fragment projection analysis6. Circular Dichroism of large systems becomes also affordable.7 References 1.O. Baseggio, G. Fronzoni and M. Stener, J. Chem. Phys., 2015, 143, 024106. 2. O. Baseggio, M. De Vetta, G. Fronzoni, M.

Europe/Rome By the eigenstate thermalization hypothesis (ETH), a highly excited energy eigenstate behaves like a thermal state. It is related to the black hole information paradox by the AdS/CFT correspondence. I will talk about ETH in two-dimensional large central charge CFT and compare the excited state of a primary operator with the thermal state. To define ETH precisely, one needs to know how similar, or equivalently dissimilar, the excited state and thermal state are. I will talk about short interval expansions of the entanglement entropy, relative entropy, Jensen-Shannon divergence. For the canonical ensemble, the excited state and thermal state are the same at the leading order of large central charge and are different at the next-to-leading order. I will also discuss briefly ETH for generalized Gibbs ensemble, and ETH for the descendant excited states. SISSA, Via Bonomea 265, Room 128 ICTP pio@ictp.it

Europe/Rome Materials are crucial to scientific and technological advances and industrial competitiveness, and to tackle key societal challenges — from energy and environment to healthcare, information and communications, manufacturing, safety and transportation. Computational science, with the current accuracy and predictive power, can play a very relevant role in this respect by boosting materials design and discovery. In this scenario, scientific objectives and computational technological perspectives are nowadays more intertwined than ever. The MaX Centre (Materials Design at the Exascale), one of the nine Centres of Excellence for computing applications funded by the EU since 2015, has been acting along two core lines, namely, high-performance computing (HPC), in view of the transition to exascale architecture, and high-throughput computing (HTC), with the final aim of building a materials modelling ecosystem. The MaX Centre takes the opportunity of its general conference to share with the scientific community its current efforts and future perspectives, as well as to underline the state of the art of both the scientific and the technological innovation which can disruptively impact on material discovery in the next decade. This conference aims at gathering scientists active in the field of materials modelling, together with HPC and HTC experts to discuss the most recent advancements in the field, including, but not limited to: Advances in high performance computing for materials science New avenues from data analytics/artificial intelligence in materials science High throughput computing for materials discovery Trends in high performance computing and codesign towards exascale Novel algorithms for first principles simulations Confirmed Invited Speakers include: Stefano Baroni, SISSA (IT) Luca Benini, Università di Bologna (IT) & ETH (CH) Stephan Bluegel, FZ-Juelich (DE) Pietro Bonfà, CINECA (IT) Luigi Brochard, Lenovo HPC (FR) Roberto Car, Princeton University, NJ (USA) Ivan Carnimeo, SISSA (IT) Juan Carrasquilla, Perimeter Institute (CA) Carlo Cavazzoni, CINECA (IT) Alessandro Curioni, IBM (CH) Thierry Deutsch, CEA-Inac (FR) Massimiliano Fatica, NVIDIA (USA) Luca Grisanti, SISSA (IT) Geoffroy Hautier, UCL-NAPS (BE) Juerg Hutter, University of Zurich (CH) Karsten Jacobsen, Technical University of Denmark (DK) Anton Kohzenvnikov, CSCS (CH) Boris Kozinsky, Harvard University (USA) Lin Lin, University of California, Berkeley, CA (USA) Stephan Mohr, BSC (ES) Pablo Ordejon, icn2 (ES) Dirk Pleiter, Juelich Supercomputing Center (DE) Deborah Prezzi, CNR Nano (IT) Maria Clelia Righi, Unimore (IT) Davide Sangalli, CNR-ISM (IT) Stefano Sanvito, Trinity College Dublin (IE) Marivi Fernandez-Serra, Stony Brook University (USA) Filippo Spiga, ARM (USA) Thomas Sterling, Indiana University, (USA) Leopold Talirz, EPFL (CH) David Wilkins, EPFL (CH) ICTP ICTP pio@ictp.it

Europe/Rome ICTP's Salam Distinguished Lecture Series is an annual presentation of talks by renowned, active scientists. The aim is to showcase important research developments as well as provide a visionary forward view. The lecture series is supported by the Kuwait Programme at ICTP. Alan Guth is the Victor F. Weisskopf Professor of Physics and a Margaret MacVicar Faculty Fellow at the Massachusetts Institute of Technology. Trained in particle theory at MIT, Guth held postdoc positions at Princeton, Columbia, Cornell, and SLAC (the Stanford Linear Accelerator Center) before returning to MIT as a faculty member in 1980. His work in cosmology began at Cornell, when fellow postdoc Henry Tye persuaded him to study the production of magnetic monopoles in the early universe. Using standard assumptions, they found that far too many would be produced. Continuing this work at SLAC, Guth discovered that the magnetic monopole glut could be avoided by a new proposal which he called the inflationary universe. Guth's honors include ICTP's Dirac Prize, the Breakthrough Prize in Fundamental Physics, and the 2014 Kavli Prize in Astrophysics. Guth is still busy exploring the consequences of inflation. He has also written a popular-level book called "The Inflationary Universe: The Quest for a New Theory of Cosmic Origins" (Addison-Wesley/Perseus Books, 1997). There will be 3 lectures, on 29, 30 and 31 January 2018, start time: 17.00 hrs. Lecture I: "Inflationary Cosmology: Is Our Universe Part of a Multiverse?" Abstract: Inflationary cosmology gives a plausible explanation for many observed features of the universe, including its uniformity, its mass density, and the patterns of the ripples that are observed in the cosmic microwave background. Beyond what we can observe, most versions of inflation imply that our universe is not unique, but is part of a possibly infinite multiverse. I will describe the workings of inflation, the evidence for inflation, and why I believe that the possibility of a multiverse should be taken seriously. Lecture II: "Eternal Inflation and its Implications" Abstract: This lecture will further explore the connection between inflation and the multiverse. I will describe the mechanism of inflation in more detail, showing why most versions lead to eternal inflation: once inflation starts, it never completely stops, but instead the inflating region grows forever, producing "pocket universes" ad infinitum. Eternal inflation is in some ways very attractive, because, for example, it offers a possible explanation for why the energy density of the vacuum is so incredibly small. But it also leads to the "measure problem": how does one define probabilities in an infinite system in which any allowed event is expected to occur an infinite number of times? Lecture III: "Infinite Phase Space and the Two-Headed Arrow of Time" Abstract: One of the unsolved mysteries of physics is the arrow of time: the laws of physics make no distinction between the future and the past, but in our experience they are entirely different. The arrow of time can be identified with the growth of entropy, but what caused the entropy to be lower in the past? I will describe a speculative picture which shows how an arrow of time can develop naturally, provided that the available phase space is infinite, even in a system with time-reversible laws of physics, and with no special initial conditions. I will also discuss the alternative possibility that the phase space available to the universe is finite, arguing that this assumption leads to serious cosmological problems. ICTP ICTP pio@ictp.it

Seminar Start Time: 17:00

Europe/Rome We present a new method to compute Renyi entropies in one-dimensional critical systems, using the mapping of the Nth Renyi entropy to a correlation function involving twist fields in a ZN cyclic orbifold. When the CFT describing the universality class of the critical system is rational, so is the corresponding cyclic orbifold. It follows that the twist fields are degenerate : they have null vectors. From these null vectors a Fuchsian differential equation is derived, although this step can be rather involved since the null-vector conditions generically involve fractional modes of the orbifold algebra. The last step is to solve this differential equation and build a monodromy invariant correlation function, which is done using standard bootstrap methods. This method is applicable in a variety of situations where no other method is available, for instance when the subsystem A is not connected (e.g. two-intervals EE).

Europe/Rome Irreversibility, which is usually quantified by the entropy production, is one of the most fundamental concepts in thermodynamics, with deep scientific and technological consequences. It is also an emergent concept, that stems from the complex interactions between a system and its environment. However, as will be discussed in this talk, the standard theory of entropy production breaks down in the quantum case, in particular in the limit of zero temperature. Motivated by this, I will present recent results which overcome these difficulties using the idea of phase space entropy measures for bosonic systems. As I will show, our theory not only overcomes the zero temperature limitations but also allows one to extend the results to deal with non-equilibrium reservoirs. As an application, we will consider squeezed thermal baths, which are instance of a grand-canonical Generalized Gibbs Ensemble and therefore allow us to construct an Onsager transport theory, akin to the theory of thermoelectricity. Finally, I will also discuss how entropy production emerges from the perspective of the environment and the system environment correlations. SISSA, Via Bonomea 265, room 128 ICTP pio@ictp.it

Europe/Rome A standard textbook picture of photovoltaic/thermoelectric/fuel cells (PTF) and biological engines (e.g. proton pumps) assumes a direct transformation of light, heat or chemical energy into electric current. However, this scheme is inconsistent with the basic principles of electrodynamics and thermodynamics. To solve this problem the mechanism of collective electric charge self-oscillations fed by a constant energy supply, has been proposed. A simple analog system - a steam engine used to propel the so-called "putt-putt boat" is used to illustrate the physics of work generation in PTF. The main new prediction of the proposed theory is the emission of electromagnetic radiation by PTF in THz or IR region, or conversely, resonant stimulation of PTF by electromagnetic oscillations. Remarkably, both phenomena has been recently observed in photovoltaic devices based on organic materials, but treated as only auxiliary effects enhancing their efficiency. ICTP ICTP pio@ictp.it

Europe/Rome Abstract: Hochschild (co)homology spaces are homological invariants of associative algebras that are useful to describe several properties of the concerned algebra. In this talk we will focus on geometric regularity. If the algebra is commutative and finitely generated, then Hochschild homology can be used to decide whether the associated algebraic variety is regular or not. In the non-commutative case, the meaning of all this is not so clear. In this talk I will first describe Hochschild (co)homology and the results that are known in the commutative setting, and I will comment afterwards on the non-commutative case. ICTP ICTP pio@ictp.it

Europe/Rome The School has the goal of teaching participating scientists about modern computer hardware and programming to provide a foundation for future computational research using High Performance Computing (HPC). Participants will go through an intensive programme with a focus on practical skills. School participants will learn to improve the efficiency of their research codes, and to parallelize them. Lectures on a selection of technical aspects of modern HPC hardware will be mixed with introductions to widely used parallel programming tools and libraries. The hands-on sessions will allow participants to practice on small example problems of general scientific interest. Example topics will cover numerical methods and parallel strategies, as well as data management. The programme specifically addresses the needs of scientists using, writing, or modifying HPC applications, and will not assume, require, or provide significant IT and HPC resource management skills. It will be mainly based on fundamental HPC-relevant features in widely used scientific software for high-performance computing: • Computer architectures for HPC and how to optimize for them • Parallel programming tools (MPI & OpenMP) • Portable, flexible and parallel I/O (HDF5) • Parallel programming best practices • Floating-point math • High-performance libraries for the solution of common math problems NOTES: • The School is organized in collaboration with the CADING-Red Group. • Accommodation and meals are covered at the campus for all selected participants.

Europe/Rome In this talk I will discuss the motion of a tracer particle driven by an external constant force through a quiescent lattice gas. Due to the interaction between the tracer and the bath particles, here modelled as an exclusion process, the driven tracer reaches a steady-state when the external force and the friction exerted by the bath balance each other. The steady-state is characterised by a non equilibrium broad inhomogeneity of the bath density surrounding the driven tracer yielding a rich variety of behaviours. I show that depending on the effective dimension of the lattice, the driven tracer exhibits from sub-diffusive to strong super-diffusive transport in the limit of high of bath particles. Moreover, when more than one driven tracers exist, the external and friction forces mediate an anisotropic attractive interacting force between the tracers, leading to the formation of clusters. I will show through numerical results that such scenario extends into continuous-space and continuous-time dynamics. SISSA, Via Bonomea 265, room 128 ICTP pio@ictp.it

Europe/Rome 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 19 February to 16 March 2018. 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. Invited Lecturers: Antonio Celani (ICTP, Trieste) Maurizio Fagotti (ENS, Paris) Chris Mathys (SISSA, Trieste) Mario Nicodemi (U. of Naples Federico II) Angelo Rosa (SISSA, Trieste) Gregory Schehr (LPTMS, Orsay Cedex) Applicants from all countries that are members of the United Nations, UNESCO or IAEA may attend. Participants should have an adequate working knowledge of English. Candidates are required to solicit recommendation letters to be sent by their supervisors in support of their application. As a rule, travel and subsistence expenses of the participants should be borne by their home institutions. However, limited funds are available to partially support some participants, who are nationals of, and working in, a developing country, and who are not more than 45 years old. Such support is limited and candidates should make every effort to secure support for their travel, at least partial. Attendance of lectures and completion of the final written tests are mandatory for those who are granted ICTP funding. There is no registration fee. ICTP ICTP pio@ictp.it

Europe/Rome The Tan's contact is an ubiquitous quantity in systems with zero-range interactions: it corresponds for example to the average interaction energy, to the weight of the tails of the momentum distribution function at large momenta, to the inelastic two-body loss rate, just to cite a few. We focus on strongly interacting one-dimensional bosons at finite temperature under harmonic confinement. As it is associated to short-distance correlations, the calculation of the Tan's contact cannot be obtained within the Luttinger-liquid formalism. We derive the Tan's contact by employing an exact solution at infinite interactions, as well as a local-density approximation on the Bethe Ansatz solution for the homogeneous system and numerical ab initio calculations for finite interactions. In the limit of infinite interactions, we demonstrate its universal properties, associated to the scale invariance of the model. We then obtain the full scaling function for arbitrary interactions.

SIDA ANNUAL REVIEW MEETINGS | (smr H552)

Seminar Start Time: 11:00

Europe/Rome There has been much progress recently in proving single-letter formulas for the mutual information (or "free energy") in high-dimensional estimation and learning problems. Computing the mutual information is important in order to locate the various "phase transitions" occurring in such problems when the noise increases or the data becomes too scarce. It is also key in computing various optimal achievable errors. Unfortunately all existing methods are highly involved, difficult to generalize and restricted in their applicability. In this talk I'll present a new method, called "adaptive interpolation method", that eliminates these barriers all at once: It is much simpler, very generic and able to tackle problems that were resisting until now. I will illustrate the method on a paradigmatic model of high-dimensional estimation, namely the "Wigner spiked model" (or "low-rank matrix factorization"). I will also briefly review some models that are now under full rigorous control thanks to this approach, as well as very recent extensions to physics models such as the "ferromagnetic p-spin model on sparse random graphs", an open problem for decades for reasons that I'll mention.

Europe/Rome In August 1859 the young and still little known Bernhard Riemann presented a paper to the Berlin Academic titled 'On the number of primes less than a given quantity'. In the middle of that paper, Riemann made a guess - remark or conjecture - on the zeros of analytic function which controls the growth of the primes. Mathematics has never been the same since. The seminar presents the captive story behind this problem, which still remains one of the most famous unsolvable problems in mathematics, and show how progress can be made on its solution employing ideas and methods which come physics, i.e. from the stochastic world of random walks and alike.

Europe/Rome Abstract: This is report on joint work with Martijn Kool. Using arguments from theoretical physics, Vafa and Witten gave a generating function for the Euler numbers of moduli spaces of rank 2 coherent sheaves on algebraic surfaces. Sheaves can be viewed as generalizations of vector bundles. Moduli spaces are algebraic varieties that parametrize the objects in which we are interested. While the Vafa-Witten formula cannot be literally true as a formula for the Euler numbers in general, we give an interpretation of it in terms of virtual topological invariants, and confirm it in many cases. We extend the results to finer topological invariants and also to rank 3. Such virtual invariants occur everywhere in modern enumerative geometry, inspired by physics, like Gromov-Witten invariants and Donaldson Thomas invariants, when attempting to make sense of the predictions from physics. Basically the idea is that the moduli spaces have very bad properties, but they "want to be" smooth, and the virtual invariants are those that they would have if they were smooth. We will try to give elementary explanations of all these concepts and their background, as much as is possible. Most of the time will be spent to just trying to explain the problem and the result. If there is time, some hints will be given about the methods. ICTP ICTP pio@ictp.it

Europe/Rome Systems out of equilibrium are characterized by a continuous exchange of energy and matter with the environment through different mechanisms, thus producing entropy at the macroscopic level. We study the entropy production of a discrete-state system with random transition rates and the injection of an external probability current. At stationarity, the entropy production is shown to be composed by two contributions whose exact distributions are evaluated in the large system size limit and close to equilibrium. The first one is related to a generalized Joule's law, while the second contribution has a Gaussian universal distribution which depends just on two topological parameters. In the second part of the talk we compare the entropy production of a Master Equation system with the one of the corresponding continuum limit, i.e. a Fokker-Planck equation. We demonstrate that the Seifert's formula for the entropy production provides just a lower bound for the exact entropy production. In fact, this formula ought to be corrected keeping into account information about the microscopic transition rates, and this correction survives in the continuum limit. This effect of the coarse-graining has shown to be glaring in the simple example of a n-step random walk. The difference between discrete-state systems and continuous systems in evaluating the entropy production has been addressed also in comparing non-equilibrium steady states, NESS, and stochastic pumping, SP. We show that the entropy production of a system with SP is greater than the one produced by a system in a NESS, generating the same (time-averaged) probability current and exhibiting the same (time-averaged) probability distribution.

Europe/Rome The grand canonical ensemble lies at the core of quantum and classical statistical mechanics. A small system thermalizes to this ensemble while exchanging heat and particles with a bath. A quantum system may exchange quantities represented by operators that fail to commute. Whether such a system thermalizes and what form the thermal state has are questions about truly quantum thermodynamics. Here we investigate this thermal state from three perspectives. First, we introduce an approximate microcanonical ensemble. If this ensemble characterizes the system-and-bath composite, tracing out the bath yields the system's thermal state. This state is expected to be the equilibrium point, we argue, of typical dynamics. Finally, we define a resource-theory model for thermodynamic exchanges of noncommuting observables. Complete passivity -- the inability to extract work from equilibrium states -- implies the thermal state's form, too. Our work opens new avenues into equilibrium in the presence of quantum noncommutation. [Based on 1512.01189 with N. Yunger Halpern, P. Faist and J. Oppenheim.] ICTP ICTP pio@ictp.it

Europe/Rome Computational biology is playing an ever-increasing important role in understanding the atomistic level details of complex biological processes, rationalizing mechanisms and predicting novel aspects, which are inaccessible, yet complementary, to experiments and identify novel drugs to interfere with biological mechanisms leading to diseases’ onset. This field evolves extremely fast, so that microsecond/millisecond time-scale simulations are nowadays routinely performed to follow the dynamics of biological systems containing up to millions of atoms. In this talk, multi-scale simulations ranging from force field molecular dynamics to hybrid quantum-classical (QM/MM) simulations, in combination with free energy techniques, will enlighten the molecular mechanisms of complex biological processes ranging from (i) the splicing mechanism in self-splicing ribozymes up to the eukaryotic spliceosome [1,2], (ii) membrane–anchored enzymes metabolizing hormones [3], and finally, (iii) to signal transmission in nuclear receptors and their polymorphic variants [4].

Europe/Rome Space Weather is the variation in Sun energy emissions, solar wind, magnetosphere, ionosphere and thermosphere, which can influence the performance and reliability of a variety of space borne and ground-based technological systems. As such Space Weather is recognised as the cause of significant errors experienced by Global Satellite Navigation Systems (GNSS), Satellite Based Augmentation Systems (SBAS) and their users. GNSS or SBAS signals, propagating from a satellite to the user receiver, pass through the ionosphere where they are subject to the damaging effects of Space Weather. Under these conditions pseudorange errors and signals scintillations at user receiver level are present. The effects are critical at low latitudes where most of the developing countries are located. The purpose of the proposed workshop is to give theoretical and practical training on the physics of Space Weather and its main effects on the GNSS operations with particular emphasis on the low latitudes ionospheric processes related to Space Weather. This workshop is the number 10 of the series of activities in the field carried out since 2009 by the ICTP T/ICT4D in partnership with the Institute for Scientific Research (ISR) of Boston College done with the collaboration of the International Committee on GNSS of the UN Office of Outer Space Affairs and The Institute of Navigation both in Trieste and in Africa. During the first day of the Workshop a review of the impact of these training efforts on the capacity building in the field in Africa and in general in developing countries will be given. Topics: Impact of the ICTP T/ICT4D Boston College ISR joint training activities on GNSS science and applications in developing countries. (Speakers from Nigeria, Cote d’Ivoire, Ethiopia, Argentina and Malaysia will describe research and academic achievements in their countries as a result of the joint training activities) Introduction to satellite navigation and positioning (Representatives of national and international institutions dealing with GNSS activities will be invited to illustrate the importance of satellite navigation for the developing countries) GNSS: systems and operations Introduction to Space Weather Continuous and transient transport of energy from the Sun to the Earth Ionosphere and its response to Space Weather with particular attention to low latitudes Space Weather effects on GNSS operations Computer Laboratory exercises on the use of Space Weather data for GNSS research and applications The deadline for submitting applications expired on 1 February 2018.

Europe/Rome Entanglement is at heart of many interesting phenomena in quantum physics. From determining important properties in many-body physics to practical communication using quantum light, understanding and proving entanglement is a paradigmatic task across many subdisciplines. It is relatively well understood for small Hilbert space dimensions, however it becomes intractably complex for large dimensions and particle numbers. In this talk I would like to give an introductory overview about state-of-the-art methods in entanglement theory for nonetheless navigating high-dimensional Hilbert spaces and reliably certifying entanglement within.

Europe/Rome Abstract: We prove the wellposedness of scalar wave equations on spatially at universe as a background with nonminimal coupling with the scalar potential turned on by introducing the k-order linear energy and the corresponding energy norm. In the local case, we show that both the k-order linear energy and the energy norm are bounded for finite time with initial data in Hk+1 × Hk. Whereas in the global case, we have to add three assumptions related to the nonminimal coupling constant, the scale factor of spacetimes, and the form of the scalar that has to be a polynomial with a small positive parameter. Then, we show that the solution does globally exist with a particular decay estimate that depends on the scale factor of the spacetimes. Finally, we provide some physical models that support our general setup. ICTP ICTP pio@ictp.it

Europe/Rome Dynamical Systems and Ergodic Theory constitute a vibrant and exciting eld of current research in pure mathematics, with lots of connections to other areas such as probability theory, differential geometry, ODEs, and potential applications to such diverse areas as natural and biological sciences, economics, engineering, climate and disease modeling and many others. It can be thought of as a modern development of classical theories of Differential Equations and the fundamental concepts and guiding ideas go back more than a century to pioneering thinkers such as Poincaré, Birkhoff and Kolmogorov. Its interest and importance has only grown in time and several Fields Medals have been awarded in the area. The ICTP-TMU School on Dynamical Systems and Ergodic Theory will consist of introductory mini-courses aimed specifically at masters and beginning PhD students who are expected to have an excellent general mathematics background but not necessarily any previous experience of the particular topics covered in the courses. The mini-courses will be complemented by a series of research-level seminars, given by internationally renowned scholars in the eld, and aimed at more advanced PhD students and local faculty and researchers.

Europe/Rome In nature, collective behaviour is a widespread phenomenon that spans many systems at different length- and timescales. Cells forming complex tissues, social insects such as ants creating dynamical structures using their own bodies, fish schools and bird flocks with their synchronous and coordinated motion are prototypical examples of the emergent self-organization which arises from local interactions among a large number of individuals. Unravelling the underlying principles and mechanisms through which such a macroscopic complexity is achieved is a fundamental challenge in biological sciences. Collective behaviour has become a unifying concept in a range of disciplines—from the spontaneous ordering of spins in ferromagnetic systems in physics, to the emergence of herding behaviour in economy, to the consensus dynamics in social sciences. Furthermore, enormous potential lies in the field of robotics in which, drawing inspiration from natural swarms, artificial collectives can be created with the abilities of the natural ones. A range of techniques have developed over recent years which allow unprecedented acquisition of quantitative empirical data, together with an enormous influx of theoretical concepts and models of collective behaviour. This upsurge enabled scientists from biology, physics, and robotics to start tackling intensively many of the open issues in this field: How is information transferred through a group? What is the structure of the underlying interaction and communication network? What is the role of the inter-individual differences (physiological, social, etc.) in a group decision-making? What is the relationship between organisms and their habitat? However, except on very rare occasions, different disciplines continue to address these problems along separate lines. Recent rapid progress in the collective behaviour field presents a well-timed opportunity to initiate a fruitful interdisciplinary discussion. The goal of this conference is to bring together experts from different scientific fields—biology, physics and engineering—to help identify new cross-disciplinary challenges, to boost the development of new ideas, and to foster the birth of an interdisciplinary community working in this field.

**DEADLINE: 31/01/2018**

Europe/Rome Every physicist has a pretty clear idea of how to define equilibrium phases of matter (e.g. using free energy considerations), whether disordered or ordered (and if ordered, a variety of situations can be encountered). By contrast, dynamics-wise, no generic and clear-cut definition a dynamical phase (disordered, intermittent, uniform, ergodicity-breaking, pattern-forming, etc) can be found. Instead, one works on a system-to-system basis. I will illustrate, on the simple example of a classical system of mutually excluding particles diffusing on a line, how a robust definition of what a dynamical phase is can be achieved. As I will go along, we will see that there may even exist transitions between dynamical phases. On a formal level, these dynamical transitions have everything in common with the quantum phase transitions that appear in hard-condensed matter. I will show that, in turn, approaching quantum problems with a classical eye, can, even with the simple example I'll discuss, lead to unexpected progress on the quantum side.

Seminar Start Time: 11:00

Europe/Rome Abstract. We shall present a phase space description of unitary matrix model. It is well known that eigenvalues of unitary matrices are like positions of free fermions. We show that in large N limit, number of boxes in Young diagram corresponding to dominant representation of SU(N) plays the role of momentum for those fermions. A relation between eigenvalues and number of boxes allows one to provide a phase space description for different large N phases of the theory. We shall consider Chern-Simons matter theory on $S^2\times S^1$ in particular and discuss how phase space description forces the corresponding dominant representations to be integrable. We also discus the level-rank duality between different dominant representations. ICTP ICTP pio@ictp.it

New directions in this multifacetted and booming field are opened by emergent 2D materials, heterostructures, multiorbital materials, and ultracold atomic mixtures, in which superconductivity and superfluidity are readily realized, and where links between observed quantum effects can be made and knowledge can be cross-fertilized. This MultiSuper conference is aimed to help understand, quantify, and manipulate the effects of hybridization between multiple condensates in a single system, as a pathway to yet unseen quantum phenomena. The key experts will be assembled to present and interpret state-of-the-art experiments and theory, and advance fundamental physics and material science in this field.

Europe/Rome Statistical mechanics and thermodynamics provide nowadays a comprehensive picture of the properties of equilibrium and near-equilibrium systems. Yet most phenomena occur out of equilibrium – for example nonequilibrium is essential for sustaining life or fluid motions – and our understanding of nonequilibrium systems is comparatively poorer and limited. At the same time, the revolution in information technologies has provided a wealth of quantitative data on complex systems whose fundamental laws are yet unknown to us. These two related domains are one of the great frontiers of contemporary science, both from the theoretical standpoint and for a multitude of practical applications. This research area has a strong interdisciplinary flavor and has special relevance for physics, geosciences, and life sciences. The understanding of complex, high-dimensional and non-equilibrium systems raises many challenges: · How does a complex system respond to perturbations? · How to construct and evaluate models across a hierarchical ladder of complexity? · How to deal with multiple scales in space and in time? · How to test theories and models against limited and often noisy observational data? · How to merge effectively models and data? · How to describe and predict large fluctuations and extreme events? · How do patterns emerge in the self-organization of complex systems? · How to study fluctuations in reversible and irreversible systems? The workshop aims to approach these problems taking advantage of results, tools, and ideas coming from a diverse range of scientific disciplines, with the goal of advancing our knowledge and foster cross fertilization.

Europe/Rome ICTP Campus - Aerial view with Miramare Castle and Park The policy relevance of understanding past, present, and future climate change and variability and the impact, response and feedbacks of natural and managed ecosystems and many different socio-economic sectors is clear. This has motivated the development of a wide spectrum of techniques and coordinated research efforts around the world aimed at generating robust regional climate change scenarios for the assessment of impacts and vulnerability and associated risks. Progress in observational and modeling capabilities, process understanding, and the development of diverse applications within the scientific, policy and practitioner communities has nurtured the scoping of an ambitious assessment of regional climate change information as part of the IPCC Sixth Assessment Report (AR6) of Working Group I (WGI). The WGI report will assess processes of global to regional climate change, weather and climate extremes in a changing climate, and climate change information for regional impact and risk assessment. A regional atlas is also proposed as an annex of the WGI report. The Expert Meeting will address the challenging assessment of regional climate information within the WGI AR6 report that will build on multiple sources of information, including observations, climate model products, downscaling techniques, and understanding of local, regional and large-scale drivers and feedbacks of regional climate and change. It will consider how regional information is used and assessed within the climate change risk assessment framework. It will It will consider the scoping of a regional atlas and the development of mechanisms to strengthen the ‘hand shake’, or integration of the assessment across the IPCC, in particular of regional impacts, vulnerability and risk undertaken by WGII. The meeting will be organized by a scientific steering committee (SSC) with representation across the three IPCC WGs, supported by the WGI Technical Support Unit. Participation is by invitation. The list of participants will be finalized following the outcome of author selection of the IPCC WG AR6 reports in early February, 2018.

Europe/Rome Abstract. In this talk, I will present two dark matter frameworks where a mass splitting in the dark sector dramatically alters the expectations for indirect detection rates. In the first case, the presence of a quasi-degenerate metastable state, where the dark matter number is stored, allows for sub-GeV relics with large s-wave annihilation cross section and not excluded by CMB bounds. In the second case, dark matter particles inelastically up-scatter in the interstellar plasma to a quasi-degenerate heavier partner, whose subsequent decays generate X-ray lines with unique spectrum and morphology.

Europe/Rome Dr. Valérie Masson-Delmotte is a senior scientist from Laboratoire des Sciences du Climat et de l'Environnement, Institut Pierre Simon Laplace, Université Paris Saclay / CEA / CNRS, France. She is the Co-chair of IPCC Working Group I for the AR6 cycle. Her research interests are focused on quantifying and understanding past changes in climate and atmospheric water cycle, using analyses from ice cores in Greenland, Antarctica and Tibet, analyses from tree-rings as well as present-day monitoring, and climate modelling for the past and the future. She has worked on issues such as the North Atlantic Oscillation, drought, climate response to volcanic eruptions, polar amplification, climate feedbacks, abrupt climate change and ice sheet vulnerability accross different timescales. She is active in outreach for children and for the general public and has contributed to several books on climate change issues (e.g. Greenland, climate, ecology and society, CNRS editions, 2016; in French). Her research was recognized by several prizes (European Union Descartes Prize for the EPICA project, 2008; Women scientist Irène Joliot Curie Prize, 2013; Tinker-Muse Prize for science and policy in Antarctica, 2015; Highly Cited Researcher since 2014). Abstract: Ice cores provide a wealth of insights into past climatic and environmental changes. Obtaining information on past polar temperature changes is important to document climate variations beyond scarce instrumental records, and to test our quantitative understanding of past climate variations. Water stable isotope ratios in ice core records have commonly been used as qualitative proxies for past changes in polar temperature and moisture source characteristics, but extracting quantitative signals is a major challenge. Initially, spatial relationships between surface snow isotopic composition and surface temperature were used to establish a modern "isotopic thermometer". Simulations performed with climate models equipped with water stable isotopes were subsequently used to assess the validity of this "isotopic thermometer calibration" for different climate states (e.g. glacial, interglacial), assuming that the ice core signal is a precipitation weighted deposition record. I will first present recent findings based on new capability to monitor water vapour isotopic composition in the North Atlantic / Greenland and several Antarctic regions. These new datasets challenge the classical interpretation of ice core records as just precipitation-weighted signals. Moreover, they challenge the ability of atmospheric models equipped with water stable isotopes to fully resolve the initial marine boundary layer isotopic composition spatial patterns. These are key limitations to our quantitative understanding of ice core signals. I will then illustrate major results obtained from water stable isotope records in Greenland and Antarctic ice cores at three time scales : (i) the documentation of polar climate variability during the last thousand years, and the challenge to separate intrinsic, spontaneous climate variability from the response to natural forcings; (ii) the bipolar structure of abrupt changes during the last climatic cycle, and its implications for the interplay between reorganizations in ocean circulation, sea ice extent and polar climate ; (iii) polar temperature trends during the current and last interglacial period, and their relevance for the assessment of ice sheet vulnerability. Over these three time scales, I will stress why quantifying past changes is relevant for the evaluation of climate models and for the assessment of future risks. The Colloquium will be livestreamed at ictp.it/livestream. Light refreshments will be served after the talk. ICTP, Trieste, Italy ICTP pio@ictp.it

Europe/Rome Abstract. Although the standard paradigm of Cold Dark Matter (CDM) has been remarkably successful in predicting the large-scale structure of the universe, it has been known to exhibit a number of problems at small scales. A popular solution to these problems involves invoking Warm Dark Matter (WDM) particles of mass about keV that erase small-scale power. The mass of these WDM particles can, in principle, be constrained using cosmological observations at high redshift. In this talk, we will explore various observational probes and the corresponding theoretical formalism which can be useful for constraining the nature of dark matter using ongoing and upcoming instruments.

Europe/Rome Spontaneous avalanche to plasma splits the core of an ellipsoidal Rydberg gas of nitric oxide. Ambipolar expansion first quenches the electron temperature of this core plasma. Then, long-range, resonant charge transfer from ballistic ions to frozen Rydberg molecules in the wings of the ellipsoid quenches the centre-of-mass ion / Rydberg molecule velocity distribution. This sequence of steps gives rise to a remarkable mechanics of self-assembly, in which the kinetic energy of initially formed hot electrons and ions drives an observed separation of plasma volumes. These dynamics adiabatically sequester energy in a reservoir of mass transport, starting a process that anneals separating volumes to form an apparent glass of strongly coupled ions and electrons. Short-time electron spectroscopy provides experimental evidence for complete ionization. The long lifetime of this system, particularly its stability with respect to recombination and neutral dissociation, suggests that this transformation affords a robust state of arrested relaxation, far from thermal equilibrium. We argue that this state of the quenched ultracold plasma offers an experimental platform for studying quantum many-body physics of disordered systems in the long-time and finite energy-density limits. The qualitative features of the arrested state fail to conform with classical models. Here, we develop a microscopic quantum description for the arrested phase based on an effective many-body spin Hamiltonian that includes both dipole-dipole and van der Waals interactions. This effective model offers a way to envision the quantum disordered non-equilibrium physics of this system. ICTP ICTP pio@ictp.it

Europe/Rome ATTENTION in the 1st week the MORNING lectures are taking place at the Leonardo building, Budinich Lecture Hall. All AFTERNOON sessions and the 2nd week will take place at the Adriatico Guest House! The ICTP regional climate modeling system RegCM4 is currently participating to the CORDEX-CORE initiative, which entails the completion of a new set of downscaled climate projections over most CORDEX domains for two greenhouse gas concentration scenarios (RCP8.5 and RCP2.6) at a horizontal grid spacing of 25 km. These projections are being completed at ICTP as well as other laboratories using the RegCM4 model, as a community effort aimed at producing climate information usable for impact assessment studies and contributing to the activities of the Intergovernmental Panel on Climate Change (IPCC). It is expected that by the date of the workshop a number of new projections will have been completed for multiple domains, and therefore the workshop will be an optimal venue to analyze these projections and exchange experience across different domains and regions. 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 the use of the RegCM modeling system. The focus of the present workshop will be on the analysis and interpretation of the output of regional model projections, addressing issues such as : assessment of model performance, performance metrics a and model systematic errors, identification and quantification of added value, study of phenomena relevant to different regions, uncertainty in projections and their dependence on model biases. The workshop will also provide a forum to discuss the production of scientific publications by the RegCM user community participating to the CORDEX-CORE effort, particularly in view of relevant IPCC deadlines. Experience with the RegCM modeling system and with the analysis of regional model output is an important requirement for participation. The workshop is intended for scientists and graduate students working in the areas of Atmospheric Physics and Dynamics, Climatology, Oceanography, Physics and Mathematics. ICTP ICTP pio@ictp.it

Europe/Rome The Schur process is in some sense a discrete analogue of a random matrix. Their edge behavior are known to be in the same universality class, described by the Airy kernel and the Tracy-Widom distribution. In this talk we consider two variants of the Schur process: the periodic case introduced by Borodin, and the "free boundary" case recently introduced by us. We are able to compute their correlation functions in a unified manner using the machinery of free fermions. We then investigate the edge asymptotic behavior and show it corresponds to two nontrivial deformations of the Airy kernel and of the Tracy-Widom distribution.

Europe/Rome The Summer School on Modelling Tools for Sustainable development will provide training on selected open modelling tools for sustainable development pathways. The Summer School involves four weeks of intensive training for government officials from countries participating in, amongst others, UNDESA, UNDP, World Bank Group and related capacity development projects on modelling tools. It will also engage academics and researchers working in the field of sustainable development whose institutions will become regional centres of excellence. As one of several entry points analysts will be exposed to geospatial electricity access (using the OnSSET.org tool) as well as medium to long term energy investment modelling (using the OSeMOSYS.org tool). Participants will then extend this to include integrated Climate-, Land-, Energy- and Water- system (using the OsiMOSYS.org) modelling. The latter will investigate the benefits of resource policy coherence. During the first week of training steering committee meetings of experts dedicated to the development of these tools will also be held (in parallel to the training). The same experts will be involved in introductory presentations. The RGCM and SPEEDY climate models of the ICTP will also be introduced in the first week. During the second to the third week participants will deepen their modelling skills so that they can operate and enhance their national models independently, incorporate new and evolving policy issues and contribute to the practice of providing rigorous evidence for decision making on national sustainable development policies. In the fourth week, presentations (by participants) will be made to high level policy makers. This will be followed by a one day high level policy discussion. The workshop will culminate with an exercise by trainers, trainees, academics, funders and others to enhance the efficacy of global capacity building for sustainability. Participation in the event will be primarily by invitation only. However, limited spaces are available for self-funded participants. The self-funded applicants are limited to academics, researchers and graduate students working on related fields, preferably working in (or with developing countries). The self-funded participants must be from a university that plans to implement teaching activities using OSeMOSYS.org, OnSSET.org or OSiMOSYS.org. A letter of commitment should be obtained from the appropriate person responsible - and submitted with the application. (Note that all teaching material from the course, can be used for the course. There are online discussion fora. Also, note that all software is free and open source.) Applications will be evaluated by the selection committee based on the following criteria: i) Relevance of their academic background to the research field(s) of the Summer School, ii) Excellent language skills iii) Clear potential and ambition to contribute to the adoption of related teaching and training in developing country institutions. The program is open for applications from all countries. Visa support may be provided.

Extrinsic flows have important applications to the geometry of submanifolds, as their study provides an effective strategy for obtaining topological classification results and for proving sharp geometric inequalities. In a broader context, extrinsic flows arise in describing the dynamics of interfaces in physical and biological sciences, a fact that provides a strong scientific motivation for their mathematical inquiry. Virtually all the different approaches to mean curvature flows will be accounted for, with particular emphasis on the fundamental problem of singularities formation. A major goal of the School will indeed be putting the best students in the position of understanding the many open problems in the field. LIST OF LECTURERS S.

Europe/Rome The emerging field of compartmentalized in vitro evolution, where selection is carried out by differential reproduction in each compartment, is a promising new approach to protein engineering. From a practical point of view, it is important to know the effect of the increase in the average number of genotype bearing agents per compartment. This effect is also interesting on its own in the context of primordial evolution in the hypothetical RNA world. The question is important as genotypes with different phenotypes in the same compartment share their fitness (the number of produced copies) rendering the selection frequency-dependent. I will show the results of a theoretical investigation of this problem in the context of selection dynamics for a simple model with an infinite population that is periodically redistributed among infinite number of identical compartments, inside which all molecules are copied without distinction with the success rate as a function of the total genomic composition in the compartment. Surprisingly, with a linear selection function, the selection process is slowed down only approximately inversely proportional to the average number of individuals per compartment. I will also demonstrate exact forms of the governing equations for some nonlinear selection functions. Finally, I will expose an intriguing open problem of an apparent phase transition for an exponential selection function seen in numerical experiments, which is missed by the current infinite population theory.

Europe/Rome Chagas disease, caused by the parasite Trypanosoma cruzi, is widespread in Latin America, where the disease remains one of the major public health problems, with an estimation of 8 million infected people and 10 000 deaths per year. This condition is mostly transmitted by insects, known as kissing bugs, belonging to the Triatominae family (Hemiptera), which are obligate haematophagous insects all their life. More than 150 species have been described in the world. While the majority lives in the wild, some of them are highly associated to the human beings, living in or around the dwellings. They typically stay hidden in the wall or roof cracks of homes, going out at night to feed on human blood. The correct determination of the species involved in the transmission of the disease is crucial to develop efficient control strategies. This can be achieved by keys of determination for adult stages, or by molecular technics. Both technics are time and/ or money consuming, showing the needs of new identification methods, especially for nymphal instars. These last years, various publications demonstrated the potential of infrared spectroscopy in insect taxonomy. Bolivia is a highly endemic country for Chagas disease. The main vector, Triatoma infestans, lives on about 60% of the territory. In total, 17 species of triatomines are reported in the country, among them Triatoma sordida and Triatoma guasayana which are reported as secondary vectors. These two species are sympatric and morphologically similar, and so they are difficult to discriminate. The goal of this study was to develop a classification model, using living nymphal and adult stage of these three species. 1293 spectra were taken in the invisible and near-infrared range. Different models were built, using different pre-processing methodologies of the spectra, and different types of feature selection. The performance of each model was evaluated for each species. After their comparison, the best model was tested on a different set of specimens where it showed a global accuracy of 97% (95-99%), an F1 score greater than 0.95 and a specificity greater than 0.94. This result shows that using infrared spectroscopy is a good strategy to predict the triatomine species. It is the first investigation to report the ability to identify juvenile instars, and moreover with a single model together with the adult stage. ICTP ICTP pio@ictp.it

Europe/Rome Moduli spaces of stable pointed curves play an important role in algebraic geometry. This School will have one course on vector bundles of coinvariants and on conformal blocks and another one on their cohomology classes in relation with those of moduli of abelian varieties. The cohomology of moduli spaces of curves and abelian varieties carries several natural classes. We focus on the tautological classes and the cohomology classes related to spaces of modular forms. The problem of determining relationships between the tautological classes turns out to be particularly interesting. Moduli spaces of curves carry vector bundles of coinvariants and conformal blocks; they are invariants of a curve C attached to a Lie group G that are canonically isomorphic to global sections of an ample line bundle on the moduli stack of certain G-bundles on C. These are generalized theta functions in case C is smooth. In case g=0, the bundles of co-invariants are globally generated, and their first Chern classes are semi-ample line bundles on the moduli of curves, and shed light on its birational geometry. We can also use the moduli space of curves to learn about generalized theta functions. TOPICS: Cohomology classes on moduli of curves and abelian varieties moduli spaces of curves and abelian varieties properties of the moduli spaces and their compactifications natural cohomology classes and their relations tautological classes and cohomology classes related to spaces of modular forms Vector bundles of coinvariants and conformal blocks introduction to moduli spaces of curves open problems and F-conjecture vector bundles of coinvariants and conformal blocks case g=0: global generation and semi-ample divisors any genus: nef divisors Chern classes of bundles of coinvariants Global sections of ample line bundles on Bun_G(C): smooth and nodal case PARTICIPATION: Women are particularly encouraged to apply.

Europe/Rome The partial transpose of density matrices in many-body systems has been known as a good candidate to diagnose quantum entanglement of mixed states. In particular, it can be used to define the (logarithmic) entanglement negativity for bosonic systems. In this talk, I introduce partial time-reversal transformation as an analog of partial transpose for fermions. This definition naturally arises from the spacetime picture of partially transposed density matrices in which partial transpose is equivalent to reversing the arrow of time for one subsystem relative to the other subsystem. I show the success of this definition in capturing the entanglement of fermionic symmetry-protected topological phases as well as conformal field theories in (1+1) dimensions.

Europe/Rome Models for active matter have brought a new type of experiments in statistical physics where the source of nonequilibrium lies within the particles themselves or on their surface. In this talk, I will take the viewpoint of molecular simulations to study matching experiments on chemically-powered nanomotors: self-propulsion by symmetry-breaking, chemotaxis, sedimentation and anisotropic nanomotors. I will comment on the design of consistent microscopic models with respect to energy conservation, to chemical kinetic, and to thermal fluctuations. As a perspective, I will discuss enzyme nanomotors. On the one hand, they consist in elaborate catalytic devices with interesting thermodynamic properties and on the other hand they might inspire or serve as molecular scale machine for nano- and bio-technology in the coming years.

Europe/Rome The climate community is still faced with large uncertainties in estimating possible climate changes in the next decades and quantifying the relative role of anthropogenic contribution to climate change. Although most modern climate models are able to reproduce reasonably well global climatologies and patterns of interannual variations, they still struggle with pervasive biases and the representation of some of the climate phenomena involving the interaction and coupling between the atmosphere, the ocean and the cryosphere. The problem is compounded by the limited understanding of some of the physical mechanisms giving rise to both our present mean climate and its natural variability at different time scales. One possible way forward is the use of a hierarchy of models to tackle the most pressing questions in climate dynamics and modeling. Key among them, is whether the climate is stable, or whether internal feedbacks could lead to tipping points, abrupt changes, and transitions to fundamentally different equilibria. Changes in the oceanic overturning, ice-albedo effects, land-surface and vegetation coupling to the atmosphere, and radiative-convective properties of the atmosphere have all been suggested as possible causes of instability in the climate system. Advances in our understanding, quantification, and modelling of these processes are necessary both for the interpretation of the paleoclimate record and for the projection of possible future climate states. A variety of studies have found that multiple equilibria exist both in highly idealized and more comprehensive models of the climate system. Whether multiple equilibria do exist in state-of-the-art climate models is still a subject of controversy. A fundamental understanding of key processes within a hierarchical modeling framework will eventually translate into a better representation and simulation within state-of-the-art climate models, as it brings new insights for process-based evaluation of climate model reliability and fit for purpose. The use of hierarchies additionally promotes the use of standardized performance metrics and highlights instances when post-processing approaches (e.g. bias correction) or diverse model tuning practices should be explored. The school will be based on lectures on theoretical aspects of atmosphere, ocean and climate dynamics, with a focus on the present state of established knowledge and relevant mechanisms. The topic of the school, Multiple Equilibra in the Climate System, will be the subject of afternoon lectures, giving an overview of the most recent progress and hypotheses suggesting the existence of multiple equilibrium states, and consequences for past and future climates. Afternoons will also be devoted to practical sessions, involving the use of simplified climate models and analysis of relevant data sets.

Speaker(s): Dr. Emilio Kropff, National Scientific and Technical Research Council’s (CONICET) Instituto de Investigeciones Bioquimicas de Buenos Aires (IIBBA), Argentina

Emilio Kropff was born in Bariloche, Argentina. He studied Physics in the University of Buenos Aires, where in 2003 he defended his thesis on the statistical mechanics of simple unsupervised learning models. In 2007 he got his PhD in Cognitive Neuroscience at SISSA (Trieste) under the supervision of Alessandro Treves, defending his thesis on analytical and computational models of human semantic memory. The next year he moved to the Kavli Institute in Trondheim, Norway, as a postdoc fellow under the supervision of Edvard and May-Britt Moser (Nobel Laureates in Physiology or Medicine, 2014). The experiments he performed in Norway led to the discovery of speed cells, a previously unknown neural type belonging to the GPS circuity. In 2012 he established in Buenos Aires, where he is a national council (CONICET) researcher at the Leloir Institute. He currently works on electrical and optical recordings of neural activity in behaving rodents, complemented with analytical and computational models, with the aim of understanding how mammals form memories and orient themselves in space. His work has been published in high impact journals such as Science and Nature. Recent honors include the FIMA-LELOIR prize (2017), the Grass Fellowship (2018) and the ICTP prize (2017).

Europe/Rome The Workshop follows the ICTP Summer School on Theory, Mechanisms and Hierarchical Modelling of Climate Dynamics: Multiple Equilibria in the Climate System. Reliable projections of tropical rainfall changes are key to any climate adaption efforts in a warming world. Yet, our global climate models are a subpar tool for the task: their spatial resolution is too coarse to reproduce the deep convection that produces most rainfall in the tropics, and current parametrizations are inadequate – as signified by persistent biases in the simulation of the annual and diurnal cycles of rainfall in large areas of the oceans and continents, as well as the response to forcing of the past. Nonetheless, tropical rainfall is organized in the large-scale structures of the monsoons and the ITCZ whose dynamics are shaped by large-scale energetic and momentum constraints that involve the global circulation of both the ocean and the atmosphere. This suggests that building a coherent understanding of tropical rainfall can benefit from an understanding of these large-scale influences and their coupling with small scale cloud and precipitation processes. Making this link across scales to improve our understanding and our ability to anticipate future tropical rainfall changes is a key question in climate science. The workshop, building on the knowledge and practical skills acquired during the school, aims to bring together expertise on large-scale atmospheric and oceanic dynamics, small scale cloud and precipitation processes, hierarchical climate modeling and observation. The aim is to both review recent progress on tropical rainfall dynamics and to identify areas where progress is most amenable in the future given the existing and emerging modelling tools and theoretical frameworks.

Europe/Rome The AdS/CFT correspondence conjectures an exact equivalence between string theories in anti-de-Sitter space and gauge theories. This correspondence and its generalizations allow one to address difficult problems of strongly coupled field theory dynamics - such as the computation of Wilson loops - using weakly coupled gravity. The other way around, it also allows one to tackle fundamental questions of gravity - such as the quantum entropy of black holes - using field theoretic methods. A very important theoretical development of the last decade has been the advent of exact results in supersymmetric field theories using the methods of localization. These methods often reduce path-integrals to finite-dimensional integrals, which in many situations can be computed exactly. Being exact, localization results are most fruitfully applied at strong coupling, and thus provide a powerful framework for producing and exploiting AdS/CFT results. In particular, the interplay of localization and the AdS/CFT correspondence provides a fertile ground to answer precise questions about the entropy of string theoretic black holes and the expectation values of Wilson loops. This School aims to provide the necessary knowledge to work at the interface of supersymmetric localization and holography, through a series of pedagogical lectures by individual speakers. The activity is intended for students in theoretical physics or mathematics and postdocs with knowledge of quantum field theory, general relativity and string theory. TOPICS: Supersymmetric localization 4D N=2 supergravity AdS black hole entropy Localization in supergravity Wilson loops Quantum entropy of black holes LECTURERS include: Francesco BENINI (SISSA) Joao GOMES (University of Amsterdam) Sameer MURTHY (King's College London) Ioannis N.

Europe/Rome Goals and brief description of the conference Defects in crystalline solids are ubiquitous. It is the second law of thermodynamics that gives rise to the appearance of a certain amount of disorder in crystalline materials at finite temperatures. Moreover, defects can be present in synthetic materials well above the equilibrium concentration due to the imperfections of material production processes or due to the exposure of the system to irradiation with energetic particles. Such lattice imperfections have a strong influence on the electronic, optical, thermal, and mechanical properties of the solids, normally deteriorating their characteristics. However, defects not always have detrimental effects on material properties, with the most prominent example being the doping of semiconductors by controllable introduction of impurities using ion implantation. In general, treatments of solids with beams of energetic ions and electrons have been shown to be a very powerful tool for the post-synthesis tailoring of material characteristics. The goal of the conference is to bring together active researchers in the field, as well as several experts in the related areas, to discuss "state of the art" in theory and experiment dealing with the physics of defects in solids. The effects of impurities and point/line defects on various properties of solids will be addressed, and the attendees will be able to learn not only the experimental facts, but also understand how the defects are treated within the framework of computational and analytical methods in theoretical physics. Particular attention is going to be paid to defects in nanomaterials, as the reduced dimensionality strongly affects their behavior. The Program will include about 20 oral presentations given by invited speakers, a poster session, and a limited number of short talks selected from contributed abstracts. Topics to be addressed Modern techniques (Raman spectroscopy, STM, XPS, TEM, etc.) used to assess concentration of defect in solids and identify their types First-principles modeling of native defects and impurities Ion and electron irradiation-induced defects Simulations of ion impacts onto solids Defects in superconductors Defects in low-dimensional materials (graphene, inorganic 2D materials, nanotubes etc.) Topological defects Defects for quantum computing Tutorial The conference will be preceded by a half-day tutorial where an introduction to the techniques used to characterize the defects will be given, along with the modern computational techniques used to get theoretical insights into defect behavior.

Europe/Rome This is a three-week school and workshop on homological methods in algebra and geometry. The first two weeks will be a school for students from East Africa and beyond. International and African researchers will join for a workshop in the third week. The school begins with two introductory courses on some basic techniques that are widely used in the area. These are then built upon in the second week with slightly more advanced topics. The goal here is to give the participants a glimpse into some ideas used in algebraic geometry and homological algebra with the hope of inspiring them to pursue further research in a related topic. The school is intended for advanced graduate students (M.Sc. and Ph.D.) and young academic staff members from East Africa and beyond. Senior academic members are also welcome to participate. In the last week, the activity turns into a research focus-session involving international and African experts. The focus-session will study tensor categories and how they arise naturally in algebraic geometry with the aim of exploiting them using homological algebra.

A very important theoretical development of the last decade has been the advent of exact results in supersymmetric field theories using the methods of localization. These methods often reduce path-integrals to finite-dimensional integrals, which in many situations can be computed exactly. Being exact, localization results are most fruitfully applied at strong coupling, and thus provide a powerful framework for producing and exploiting AdS/CFT results. In particular, the interplay of localization and the AdS/CFT correspondence provides a fertile ground to answer precise questions about the entropy of string theoretic black holes and the expectation values of Wilson loops. This Workshop aims to bring together experts in the areas of supersymmetric localization and holography, to provide cross fertilization and outline key directions for the future.

Europe/Rome Aim of the workshop The workshop on the emerging field of biological operations research – the application of operations research methodologies in systems and molecular cell biology – is designed to bring together participants and lecturers versed in either of the two disciplines that are eager to further uncover the deep connections between the two fields and find new avenues for research and collaboration while gaining new insight on biological functions from an operational and system perspective. The long-term goal of the workshop is to boost research and collaboration in this field, by acquainting researchers with the existing long-standing problems in system biology, molecular cell biology and bacterial physiology. We will explore the deep connections between these problems and those that arise in operations research, e.g. the question of regulation of mass production in an uncertain market, dynamic resource allocation, scheduling problems and the impact of different queuing disciplines of speed and efficiency of a complex production facility. Researchers will have a chance to exchange ideas and compare different methodologies and modes of thinking about operational parameters such as throughput, efficiency, resource allocation, reliability, redundancy, and cost in a novel biological context. Topics Scheduling and queuing disciplines – from circadian rhythms to pipelining of self-replication Allocation of resources to self-replication vs. maintenance Transcription and translation regulation, role of external and internal information Controlling WIP (work-in-progress) – Kanban, TOC, and CONWIP vs. product feedback inhibition Anticipatory systems and their reverse engineering Metabolic networks and queuing theory Bullwhip effect and the role of inventory control, forecasting and information Modern queuing theory Self-regulating and resource dependent branching processes ICTP ICTP pio@ictp.it

Europe/Rome Abstract. In principle, we expect that our cosmos has experienced a series of complicated phase transitions. Exploring the corresponding consequences and discriminating between various types of mentioned phase transitions are therefore of interest not only from theoretical approaches but also from observational points of view. In this talk, relying on an extensive simulation of cosmic strings networks, I examine the CMB random field induced by a typical topological defects which is so-called cosmic strings as a part of ISW phenomenon. I will use various robust topological measures accompanied by some multi-scale reductions to quantify our ability to detect the probable cosmic strings networks. To this end I also utilize extensive Machine learning algorithm to find best feature sequences which are more sensitive for searching such one-dimensional defect.

Europe/Rome Erol Gelenbe is currently the “Dennis Gabor” professor in Electrical and Electronic Engineering at Imperial College. He received a PhD on “Stochastic Automata with Structural Restrictions” from the Polytechnic Institute of New York (NYU), and a Doctor of Science degree on “Modeles de Performances de Systemes Informatiques” from University Pierre et Marie Curie (Paris). A Fellow of ACM and IEEE and of several National Academies, his honours include the Commendatore al Merito of Italy and France’s Legion d’Honneur. He was awarded Doctorates Honoris Causa by the University of Rome Tor-Vergata, the University of Liege (Belgium) and Bogazici Universty (Istanbul). Abstract: The biological sciences have long been a source of inspiration in the design of solutions for complex problems posed by operations research. Neuronal model-based optimization, prey-predator models and food webs, ant colony optimization, reinforcement learning, data classification with neural networks, learning-based techniques for tracking and control, are some widely used techniques in operations research that have been inspired by nature. This lecture will delve deeper into this interface. I will first discuss spiking random neural networks and show that the Random Neural Network (RNN) is a rigorous mathematical model with function approximation capability and a remarkable product form solution, whereby in equilibrium the joint probability distribution of an arbitrarily large set of fully connected spiking neurons have a joint probability distribution which is the product of the marginal distributions of individual neurons. This initial discovery provided a rigorous basis for fast gradient and deep learning, which has been exploited in numerous applications, including the design of a Cognitive Packet Network that is controlled via neuronal distributed intelligence to enhance Quality of Service and Security. The RNN has also been be used to provide more “truthful” information from web searches. The RNN has been generalized, giving rise to a branch of Queueing Theory called G-Networks which allow the rigorous prediction of the performance of distributed computer systems and data networks which incorporate dynamic control functions such as state dependent rerouting, load balancing and the elimination of overload, the reset of a system after failures, and the ability to modify a sub-system’s state with knowledge from other sub-systems. In this talk, in addition to the RNN and G-Networks, I shall also discuss how such models can be applied to the analysis of Gene Regulatory Networks and the detection of anomalies from micro-array data. The Colloquium will be livestreamed from the ICTP website. Light refreshments will be served after the event. All are welcome. ICTP, Trieste, Italy ICTP pio@ictp.it

Europe/Rome Vladan Vuletić is Lester Wolfe Professor of Physics at MIT. Born in Serbia (Yugoslavia), and educated in Germany, he earned the Physics Diploma and a PhD from the Ludwig-Maximilians-Universität München. He was postdoc and Assistant Professor in the Department of Physics at Stanford University before joining MIT in 2003. Vuletić’s research in experimental atomic physics focuses on entanglement in many-body systems for uses in precision measurements, quantum simulation, and potentially quantum computing. Major achievements include spin squeezing for overcoming the standard quantum limit in atomic clocks, the development of laser cooling techniques for Bose-Einstein condensation, and the first observation of bound states of photons. Abstract: Recent years have seen a remarkable development in our ability to manipulate matter and light at a quantum level. Quantum simulators with individual trapped atoms are becoming a reality, and quantum computing is on the verge of becoming experimentally viable. Of particular interest are tunable strong interactions between atoms that can be used to experimentally implement and control entangled many-body states. Highly excited, metastable atomic Rydberg states can be used to implement controllable long-distance interactions between individual quanta. I will discuss two applications: By coherently coupling light to Rydberg excitations in a dense atomic medium, we have realized a highly nonlinear optical medium where the interactions between individual photons are so strong that two photons can even form a bound state. I will also discuss the use of Rydberg interactions to realize a many-atom quantum simulator with up to 51 individually trapped atoms, where we have observed a quantum phase transition towards a state with antiferromagnetic order, as well as long-lived many-body oscillations after a sudden quench. The event will be livestreamed from the ICTP website. All are invited to attend. Please note unusual venue and time! ICTP, Trieste, Italy ICTP pio@ictp.it

Europe/Rome Week 1 A circle of concepts and methods in dynamics. Basic concepts in dynamics will be introduced, with many examples, especially in the setting of circle maps. Topics include rotations of the circle, doubling map, Gauss map and continued fractions and an introduction to the basic ideas of symbolic codings and invariant measures. At the end of the week we will discuss some simple examples of structural stability and renormalization. Week 2 Ergodicity in smooth dynamics (10h, Jana Rodriguez-Hertz and Amie Wilkinson) The concept of ergodicity is a central hypothesis in statistical mechanics, one whose origins can be traced to Boltzmann's study of ideal gases in the 19th century. Loosely speaking, a dynamical system is ergodic if it does not contain any proper subsystem, where the notion of "proper" is defined using measures. A powerful theorem of Birkhoff from the 1930's states that ergodicity is equivalent to the property that "time averages = space averages:" that is, the average value of a function taken along an orbit is the same as the average value over the entire space. The property of ergodicity is the first stepping stone in a path through the study of statistical properties of dynamical systems, a field known as Ergodic Theory. We will develop the ergodic theory of smooth dynamical systems, starting with the fundamental, linear examples of rotations and doubling maps on the circle introduced in Week 1. We will develop some tools necessary to establish ergodicity of nonlinear smooth systems, such as those investigated by Boltzmann and Poincaré in the dawn of the subject of Dynamical Systems. Among these tools are distortion estimates, density points, invariant foliations and absolute continuity. Closer to the end of the course, we will focus on the ergodic theory of Anosov diffeomorphisms, an important family of "toy models" of chaotic dynamical systems. Renormalization in entropy zero systems (5h, Corinna Ulcigrai) Rotations of the circle are perhaps the most basic examples of low complexity (or "entropy zero") dynamical systems. A key idea to study systems with low complexity is renormalization. The Gauss map and continued fractions can be seen as a tool to renormalize rotations, i.e.study the behaviour of a rotation on finer and finer scales. We will see two more examples of renormalization in action. The first is the characterization of Sturmian sequences, which arise as symbolic coding of trajectories of rotations (and hint at more recent developments, such as the characterization of cutting sequences for billiards in the regular octagon). The second concerns interval exchange maps (IETs), which are generalizations of rotations. We will introduce the Rauzy-Veech algorithm as a tool to renormalize IETs. As applications, we will give some ideas of how it can be used (in some simplified settings) to study invariant measures and (unique) ergodicity and deviations of ergodic averages for IETs. ----------------------------------------------------------------------------------------- Tutorial and exercise sessions will be held regularly and constitute an essential part of the school.

Europe/Rome In an ecological system, pathogens often need to share their host with other pathogens, and therefore compete for the resources with different spreading strategies. Both cooperative and competitive interactions in bacterial infections have been observed. Here we first review recent theoretical studies addressed these two mechanisms separately and then study their combination and discuss about non-trivial dynamical effects can be expected to arise. Thus we study two strains competing with each other for host resources in the presence of a third pathogen cooperating with both of them. We first treat dynamics in a homogeneously mixed population by means of mean-field theory and stability analysis. We study the impact of cooperation on the outcome of the two-pathogen competition, which can be quantified in terms of dominance of one competing pathogen or the co-circulation of both of them. We show that the presence of a third cooperating pathogen can alter the outcome of competition as it may favor the more cooperative pathogen over the more infectious one. We then consider more complex contact structures among hosts and perform computer simulations to study the evolution of the diseases. ICTP ICTP pio@ictp.it

Europe/Rome Abstract. Starting from a generic near horizon expansion in any spacetime dimension greater than two we derive all near horizon symmetries and discover a wealth of novel results: 1. Any non-extremal horizon has an infinite set of near horizon symmetries and associated soft hair excitations. 2. The near horizon symmetries can be represented as generalization of the Bondi-Metzner-Sachs algebra. 3. For horizons that are either flat or non-rotating the near horizon symmetries can be represented as Heisenberg algebras, with one quarter of the inverse of Newton constant playing the role of Planck's constant. 4. Not only black holes, but also cosmological horizons are equipped with soft hair. We discuss implications of soft hair for horizon thermodynamics and entropy, and comment on open problems and further developments. ICTP ICTP pio@ictp.it

Europe/Rome The classical triangular antiferromagnetic Heisenberg model with Dzyaloshinskii-Moriya interactions in a magnetic field is studied. We focus in particular on the emergence of a composite spin crystal phase that was recently observed in [Phys. Rev. B 92, 214439 (2015)] for intermediate fields. This complex phase, which corresponds to a lattice of Z2 vortices, can be made up from three inter-penetrated skyrmion lattices, one for each sub-lattice of the original triangular one. We present our numerical results and the explicit construction of the low-energy effective action that reproduces the correct phenomenology. This effective action could serve as a starting point to study the coupling to charge carriers, lattice vibrations, structural disorder and transport phenomena. ICTP ICTP pio@ictp.it

Europe/Rome Abstract: Consider a quantum chain in its ground state and then take a subdomain of this system with natural truncated hamiltonian. Since the total hamiltonian does not commute with the truncated hamiltonian the subsystem can be in one of its eigenenergies with different probabilities. Since the global energy eigenstates are locally close to diagonal in the local energy eigenbasis we argue that the Shannon(Renyi) entropy of these probabilities follows an area-law for the gapped systems. When the system is at the critical point the Shannon(Renyi) entropy follows a logarithmic behaviour with a universal coefficient. Our results show that the Shannon(Renyi) entropy of the subsystem energies closely mimics the behaviour of the entanglement entropy in quantum chains. We support the arguments by detailed numerical calculations performed on the transverse field XY-chain. ICTP ICTP pio@ictp.it

Europe/Rome Abstract. The current tension in H_{0} measurements by Planck-2015 for $\Lambda$CDM and that by recent direct measurement by Riess et al. 2016, also results another tension in the value of r_{d}, the sound horizon at drag epoch, measured by BAO observations and Planck-2015. We show that, regardless of dark energy dynamics, to accommodate higher value of H_{0}, one needs a lower value of r_{d}, and so necessarily a modification of early universe cosmology. Later on, a model independent approach to constraint background evolution of the universe with low-redshift data, will be discussed. ICTP ICTP pio@ictp.it

Europe/Rome In natural systems time delays are inevitable due to the finite speed of the signal transmission over a distance, and are not negligible if they are similar to the time scales of the observed dynamics. For example in the brain, where the delays are on the same scale as the signal operation, they affect the brain performances and need to be considered. On the other hand, many complex networks, such as the cortical networks, are hierarchical. It means that their communities may be further divided into sub-communities. Therefore, because of the above-mentioned reasons, the analysis of time-delayed dynamics on hierarchical networks may help to understand the interplay between brain structure and function. Based on extensive simulations in artificial and cortical networks with homogeneous time delays, we uncovered that for a fixed coupling strength, by changing time delay different regions of coherent, multistable and incoherent dynamics are revealed. We show that in a hierarchical network, by transition from incoherent to coherent states, different topological scales of the network are revealed respectively in a non transient behavior. In addition, we find that by considering bimodal distribution of the time delays the parameter regions corresponding to the multistabe dynamics will be extended. Finally we show that the results are connected to the global slow dynamics of the brain. ICTP ICTP pio@ictp.it

Europe/Rome One-dimensional systems with short-range interactions cannot exhibit a long-range order at nonzero temperature. However, there are some particular one-dimensional models, such as the Ising-Heisenberg spin models with a variety of lattice geometries, which exhibit unexpected behavior similar to the discontinuous or continuous temperature-driven phase transition. Although these pseudo-transitions are not true temperature-driven transitions showing only abrupt changes or sharp peaks in thermodynamic quantities, they may be confused while interpreting experimental data. Here we consider the spin-\frac{1}{2} Ising-XYZ diamond chain in the regime when the model exhibits temperature-driven pseudo-transitions. We provide a detailed investigation of how this phenomenon occurs in several physical quantities, such as entropy, magnetization, specific heat, magnetic susceptibily, and correlation functions between distant spins that illustrates the properties of quasi-phases separated by pseudo-transitions. Inevitably, all correlation functions show the evidence of pseudo-transition. It is worth to mention that the correlation functions between distant spins have an extremely large correlation length at pseudo-critical temperature. ICTP ICTP pio@ictp.it

Europe/Rome Prof. J. Dalibard heads an experimental research group at CNRS-ENS and Collège de France, Paris. Pioneering recent achievements include the first observation of a Kosterlitz-Thouless transition in 2D Bose gases and studies of vortex dynamics in rotating condensates. Early in his career, J. Dalibard was responsible for key theoretical ideas in laser cooling and trapping, including polarization gradient cooling and the Magneto-optical Trap (MOT), and thus provides in his present work the link between theoretical and experimental quantum optics. He has also pioneered theoretical methods to solve the dynamics of open quantum systems utilizing quantum trajectories. Among his honors we can find the Pascal Medal of the European Academy of Science (2009), the Max Born Medal of the American Optical Society (2012), the Davisson–Germer Prize of the American Physical Society (2012), the Senior BEC award (2017), and his fellowships in the European Academy of Science, the Optical Society of America and the American Philosophical Society. Abstract: The physics of many-body systems strongly depends on their dimensionality. For example, in a two-dimensional world, most standard phase transitions towards an ordered state of matter would not occur, because of the increased role of fluctuations. However non-conventional "topological" transitions can still take place, as understood initially by Kosterlitz and Thouless. During the last decade, a novel environment has been developed for the study of low-dimensional physics. It consists of cold atomic gases confined in tailor-made light traps, forming thus a thin layer of material particles. In this talk I will present some key aspects of these quantum 2D gases, such as their transition to a superfluid state and their (approximate) scale invariance. I will also discuss out-of-equilibrium features, like the nucleation of random currents when merging independent samples. The event will be livestreamed from the ICTP website.

Europe/Rome Abstract. We present several results about solenoidal manifolds motivated by results by Dennis Sullivan in [1] with commentaries developed in [2] and on a join project with Dennis Sullivan [3]. Solenoidal manifolds of dimension n are topological spaces which are locally homeomorphic to the product of a Cantor set with an open subset of Rn. Geometric 3-dimensional solenoidal manifolds are the analog of geometric 3-manifolds in the sense of Thurston. We will give some results related to 3-dimensional geometric solenoidal manifolds.

Europe/Rome Conditions for applying in this School: Selected candidates will be expected to actively engage in the programme and present a 20' minute talk (with a time for discussion and questions included) describing own or own group's research summarizing important or recent results on wasteform, spent fuel or nuclear materials of relevance to immobilization studies. Participants are encouraged to set their work in the context of their own national waste management strategy and should first give a brief overview of the types of waste produced and managed in her/his country, and then a current status of waste conditioning and disposal practice (both by means of one or two summary slides). SCHOOL DESCRIPTION: Nuclear waste management is a core issue for sustainable development and long-term viability of nuclear energy as energy supply. The main goal of this school is the dissemination of knowledge on optimal methods of synthesis and study of crystalline and glass-crystalline wasteforms for the immobilization of actinides and other long-lived dangerous radionuclides. It aims on transferring experience of ceramic and glass-composite materials fabrication from leading experts to specialists interested in reliable immobilization of toxic nuclides. Directors: Michael I. Ojovan (IAEA), Boris E. Burakov (Radium Institute), Local Organiser: Antonello Scardicchio Description: The school will bring together researchers from the area of materials science with a focus on crystalline and vitreous materials for nuclear energy. The school will assist experts to better understand the wide range and full potential of material science applied to radioactive waste immobilisation and technology tools and methods devoted to immobilisation and properties of crystalline and glass-crystalline materials. Knowledge transfer will be facilitated between individuals from developed and developing countries, and can be used to develop further the internationally sponsored development of nuclear waste immobilisation using crystalline and glass-crystalline wasteforms. Participants should return from the school with a richer understanding of actinide immobilization technologies and the range of techniques to investigate actinide-containing materials. Topics: Fundamentals of actinide immobilization; Radiation damage effects in actinide-doped crystalline materials and glasses; Leach behaviour of actinide-doped ceramics and glasses; Advanced materials based on durable actinide host-phases; New types of Pu fuel and targets for actinide transmutation; Interaction of actinide wastes and geological environment; Modelling of actinide migration in geological environment; Actinide behaviour during severe nuclear accident (Chernobyl, Fukushima, etc.) and nuclear tests.

Europe/Rome The workshop introduces young and established nuclear scientists to the evaluation of nuclear structure and decay data, by providing an overview of experimental and theoretical nuclear techniques and basic training in the evaluation procedures and formats involved in the production of the Evaluated Nuclear Structure Data File (ENSDF). Reliable evaluated nuclear structure and decay data are of vital importance for basic nuclear physics and astrophysics, as well as for nuclear applications such as power generation, material analysis, dosimetry and medical diagnostics. These important data requirements are catered by the international network of Nuclear Structure and Decay Data (NSDD) Evaluators, created in 1974 and coordinated by the IAEA. The main output of this network is the recommended ENSDF database and evaluations published in Nuclear Data Sheets. This workshop belongs to a series of ICTP workshops that started in 2003 and have been crucial for attracting young nuclear scientists to nuclear structure and decay data evaluation and for providing them with the basic tools to pursue this activity. TOPICS: modern nuclear experimental techniques & facilities; nuclear structure models; nuclear structure and decay data: compilations and evaluations; evaluation methodologies for nuclear structure and decay data; analysis and utility codes; ENSDF editors and Web tools; databases and online retrieval software. CALL FOR PAPERS A session will be held during the workshop for participants to present their work related to nuclear structure and decay data.

Europe/Rome Director: Teketel YOHANNES, AASTU, Addis Ababa, Ethiopia ICTP Contacts: Ralph GEBAUER & Nicola SERIANI, ICTP, Trieste, Italy The Workshop addresses students and researchers working in the field of solar energy and energy storage. The event will focus on fundamental and applied research on functional materials, on devices and on their application. To cope with increasing global energy demand, solar energy is one of the best alternatives. The feasibility of solar energy technology in Africa, where the sun is available throughout the year, is not questionable. This huge energy can be used as photo-thermal and in photovoltaic forms. For efficient conversion of solar energy it is very important to have a clear understanding of the photo-physical and opto-electrical properties of materials. In parallel with the development of photovoltaic devices, due attention has to be given to the storage of electrical energy in easily portable chemical energy forms and/or in an electrical field. Since solar energy is collected only in the day time, it is also wise to develop alternative technologies such as storage for renewable energy forms. Please note that funds from the Joint Undertaking for an African Materials Institute (JUAMI) are also available for US students. TOPICS: Current photovoltaic systems, new technologies; Promise of nanostructures and technology in this field; Wind and geothermal energy: potential and installations in Ethiopia; Energy storage: fuel cells, batteries and supercapacitors; Importance of materials science, experimental and computational approach; Renewable energy potentials in the region.

Europe/Rome I will discuss walking behavior in gauge theories and weakly first order phase transition in statistical models. Despite being phenomena appearing in very different physical systems, they both show a region of approximate scale invariance. They can be understood as a theory passing between two fixed points living at complex couplings, which we call complex CFTs. By using conformal perturbation theory, knowing the conformal data of the complex CFTs allows us to make predictions on the observables of the walking theory. As an example, I will discuss the two dimensional Q-state Potts model with Q>4. SISSA, Via Bonomea 265, room 004 ICTP pio@ictp.it

Europe/Rome KINDLY NOTE CHANGED TIME - from 14:00 to 15:30 PART I In this tutorial I will describe matrix product state (MPS) ansatz and its generalization to operators, and show how it can be used to calculate unitary or dissipative quantum evolution. Such ansatz is, in many situations, rather efficient and allows one to study large many-body systems. I will explain how to write states in the canonical MPS form and how to perform transformations, preserving optimal finite-rank description. The tutorial will include blackboard exercises as well as hands-on numerical examples and will give sufficient knowledge to produce your own code. ICTP ICTP pio@ictp.it
