Europe/Rome A supersymmetric theory with osp(1|2)-invariance can be used to describe spanning (hyper-)forests on a given graph. In a sigma-model, the bosonic part of the superfield can be integrated out and the symmetry is realized non-linearly in the remaining Grassmann degrees of freedom. We investigate the invariant osp(1|2) Grassmann and Clifford subalgebras. We discover that, given an arbitrary vertex ordering, a basis of independent elements is given by terms labeled by non-crossing partitions, respectively of the vertices of the graph, and of a doubling of this set. The invariant Clifford subalgebra is isomorphic to a Temperley--Lieb Algebra, in a peculiar even/odd generalization. A relation involving four complex fermions plays a central role in the construction, and disentangles the only 4-set crossing partition as a linear combination of the other partitions with up to two blocks. This relation appears in different flavours, and equivalence of the formulations is shown. ICTP ICTP pio@ictp.it

Europe/Rome I review recent work related to the volume dependence of matrix elements of local fields (form factors), giving a description valid to all orders in inverse powers of the volume (i.e. only neglecting contributions that decay exponentially with volume). This method can be used to test exact solutions (derived using bootstrap methods in integrable models) against numerical data obtained by solving the field theory in a truncated state space; it is also useful in extracting matrix elements from numerical data such as those obtained from e.g. lattice field theory. Matrix elements with disconnected pieces require special attention. Such matrix elements are important in computing finite temperature correlation functions. I give a new method for generating a low temperature expansion, which is evaluated for the one-point function up to third order, confirming a series expansion conjectured by Leclair and Mussardo. Time permitting, I also briefly show how the results can be extended to a situation with boundaries. Lecture Room D-SISSA Main Building ICTP pio@ictp.it

Europe/Rome I review domain coarsening phenomena in the non-equilibrium dynamics of discrete spin models with Z_2 symmetry. Standard classifications distinguish between "curvature-driven" processes, in which the interface motion is driven by surface tension (e.g. Glauber dynamics), and purely diffusive processes driven by multiplicative noise at the interfaces (e.g. Voter model). There are evidences that slight changes of the microscopic Voter-like rule (e.g. adding intermediate states) leads to the emergence of an effective surface tension. We explain this phenomenon deriving a macroscopic Langevin equation for these processes and studying it with field-theoretic and numerical methods. ICTP ICTP pio@ictp.it

Europe/Rome Using the adaptive time-dependent density matrix renormalization group, we study the time evolution of strongly correlated bosonic and fermionic systems on one-dimensional lattices pushed out of equilibrium. In particular, we investigate a system of interacting spinless fermions after a sudden change in the interaction strength and a system of soft- core bosons modeled by the Bose-Hubbard model released from a trapping box-potential. By considering the momentum distribution function of the bosonic system, we demonstrate the formation of (quasi-)coherent matter waves emerging from an initial Mott insulating state over a wide range of the interaction strength between the particles. In the fermionic system, we find the density correlations to exhibit a characteristic light-cone-like time evolution which is representative of a ballistic transport of information. Such behavior is observed both when quenching an insulator into the metallic region and also when quenching within the insulating region, but not when a metallic state is quenched deep into the insulating regime. Instead, stable domain walls in the density correlations emerge during the time evolution, consistent with the predictions of the Kibble-Zurek mechanism. ICTP ICTP pio@ictp.it

Europe/Rome Measuring the transport of electrons through a graphene sheet necessarily involves contacting it with metal electrodes. We study the adsorption of graphene on metal substrates using first-principles calculations at the level of density functional theory. The bonding of graphene to Al, Ag, Cu, Au and Pt(111) surfaces is so weak that its unique "ultrarelativistic'' electronic structure is preserved. The interaction does, however, lead to a charge transfer that shifts the Fermi level by up to 0.5 eV with respect to the conical points. The crossover from p-type to n-type doping occurs for a metal with a work function ~5.4 eV, a value much larger than the work function of free-standing graphene, 4.5 eV. We develop a simple analytical model that describes the Fermi level shift in graphene in terms of the metal substrate work function. Graphene interacts with and binds more strongly to Co, Ni, Pd and Ti. This chemisorption involves hybridization between graphene p_z-states and metal d-states that opens a band gap in graphene. The graphene work function is as a result reduced considerably. In a current-in-plane device geometry this should lead to n-type doping of graphene. ICTP ICTP pio@ictp.it

Europe/Rome If an isolated quantum-mechanical many-body system is suddenly forced out of thermal equilibrium, does it relax to a new steady state or does it keep oscillating? How does the final state depend on the initial state? Recently it has become possible to investigate such fundamental questions in experiments with ultracold atomic gases. Here we study two models of interacting fermions, the Falicov-Kimball model in dynamical mean-field theory [1] and a Hubbard chain with long-range hopping [2]. We obtain the exact real-time dynamics after a sudden change of the Hubbard interaction, starting from a metallic or a Mott-insulating initial state. We observe relaxation to a new steady state, showing that the presence of the Mott gap does not inhibit relaxation. The steady-state properties are described by generalized Gibbs ensembles which take all constants of motion into account. We discuss under which conditions such ensembles provide the correct statistical description of integrable systems [2]. [1] M. Eckstein and M. Kollar, Phys. Rev. Lett. 100, 120404 (2008). [2] M.

Europe/Rome A spin polarized current may transfer angular momentum to a ferromagnet, resulting in a spin-torque phenomenon. At the same time the shot noise, associated with the current, leads to a nonequilibrium stochastic force acting on the ferromagnet. We derive a stochastic version of the Landau-Lifshitz-Gilbert equation for a magnetization of a "free" ferromagnetic layer in contact with a "fixed" ferromagnet. We solve the corresponding Fokker-Planck equation and show that the nonequilibrium noise yields to a nonmonotonic dependence of the precession spectrum linewidth on the current.

Europe/Rome Electronic Mach-Zehnder interferometers were constructed recently from chiral one-dimensional integer quantum Hall edge states. These interferometers showed an unexpected behavior of the visibility of Aharonov-Bohm (AB) oscillations in the nonlinear regime, where the visibility developed a lobe structure accompanied by the $pi$-jumps of the AB-phase [1]. We address these phenomena by studying the model of a Mach-Zehnder interferometer, where the one-dimensional electrons interact via long-range potential. We calculate exactly the visibility of the Aharonov-Bohm oscillations in this model, which agrees well with experimental results. [1] "Unexpected Behavior in a Two-Path Electron Interferometer", I.

Europe/Rome A subset $A$ of an abelian group is said to be sum-free if there is no solution of the equation $x+y =z$ with $x,y, z \in A.$ Given a subset $B$ of a finite abelian group $G$, the set $B+B$ consists of all those elements of $G$, which can be written as a sum of two elements of $B$. We say that a set has small sumset if the cardinality of $B+B$ is not much larger in compare to the cardinality of $B.$ In a joint work with R. Balasubramanian and D.S. Ramana, we observe that in certain groups, the question of counting the total number of sum-free sets is related to the question of counting the number of sets with small sumset. In another work, we obtain an upper bound for the number of sets with small sumset. Using this one obtain an upper bound for the number of sum-free sets in a finite abelian groups of "type III" which is substantially better than the bound implied by the result of Ben Green and Imre Ruzsa. Moreover using this, one also obtain an existence of Ramsey graphs among Cayley graphs and thereby proving a weaker version of a conjecture of Noga Alon. ICTP ICTP pio@ictp.it

Europe/Rome The theoretical problems involved in conservation biology and natural resource management are rapidly emerging as a deep area of intellectual inquiry. These problems are inherently non-linear, and can rapidly become complex, as found in the emerging areas of Biocomplexity, Bioeconomics, and Sustainability Science. Capacity building in these areas will be central to the sustainable management of natural resources and the conservation of ecosystems. The workshop will focus on mathematical models related to problems in natural resource management, climate change and conservation biology in the context of ecological networks. It will consist of a series of intensive lectures along with hands-on computer demonstrations and group exercises. Specifically, group sessions will be organized in which participants from different regions of the world will address specific issues in conservation and natural resource management in changing environments. Each group will give an oral presentations of the outcome of their work at the end of the workshop. Topics covered will include: •Population dynamics and optimal management of renewable resources; •Population viability and risk analysis; •Biocomplexity and the structure of ecological networks; ecological community structures; •Fragmentation and persistence; •Effects of climate change on species distributions, infectious diseases and ecosystems. A series of background keynote lectures on specific topics and examples will be given by the four organizers and the guest lecturers.

Europe/Rome Dynamical systems quenched from a disorder into an ordered phase, may display coarsening phenomena. The simplest example is the Ising ferromagnet. When the system is cooled rapidly through the transition temperature, domains of the two ordered phases form and grow (coarsen) with time. In the present work we obtain the exact result for the statistics of the areas enclosed by domain boundaries for the coarsening dynamics of a nonconserved scalar field in two dimensions. This result represents the first analytical demostration of the dynamical scaling hypothesis for this system. These results can be also generalizated to the coarsening dynamics under the effect of finite temperature or the presence of quenched disorder. All these results have been tested with simulations on the two-dimensional square-lattice Ising model using a Montecarlo algorithm. We have also done experiments on the coarsening dynamics of liquid crystals. It was proposed that deracemization in this system is a curvature-driven process. We test this prediction using our exact result for the distrubution of areas. We demonstrate that deracemization in such liquid crystals belongs to the Allen-Cahn universality class, and that the exact formula, can be used as a strict test for this dynamic universality class.

Europe/Rome It is shown that, for pertinent values of the fabrication and control parameters, an attractive finite coupling fixed point emerges in the phase diagram of a Y-junction of superconducting Josephson chains. The new fixed point arises only when the dimensionless flux f piercing the central loop of the network equals \pi. A detailed account of the Josephson current-phase relationship along the arms of the network, near each one of the allowed fixed points, is provided. The results evidence remarkable similarities between the phase diagram accessible to a Y-junction of superconducting Josephson chains and the one found in the analysis.

Europe/Rome We show that the large distance behavior of the density-density correlation function of a weakly confined Random Matrix ensemble can be exactly reproduced by a Gaussian scalar field theory in a curved two-dimensional space-time characterized by the presence of a singularity and of an event horizon. Therefore, we propose this as a low-energy effective theory describing the ensemble, in analogy to what has been done for other invariant ensembles and Luttinger Liquid theory. The presence of an event horizon in the curved space-time naturally gives rise to a the phenomenon known as Hawking radiation. A similar mapping with another gravitational analogue model has been shown to exist with a Bose-Einstein condensate pushed to flow at a velocity higher than its speed of sound. In this case the Hawking radiation is composed of sound waves propagating over the cold atoms. Our work suggests a three-fold connection between a moving BEC system, black-hole physics and unconventional RMEs. ICTP ICTP pio@ictp.it

Europe/Rome The Backward Fokker-Planck Equation (BFPE) provides an elegant technique for solving a number of first-passage problems. After an introduction to the method, the usefulness of the BFPE will be illustrated by applying it to a number of problems of increasing complexity, namely (i) the simple random walk with an absorbing boundary at the origin; (ii) the simple random walk with an absorbing boundary moving with constant velocity; (iii) the simple random walk with two absorbing boundaries moving at different velocities, and (iv) the random walk in the presence of various types of "shear flow" and an absorbing boundary at the origin. The last of these is a problem with very rich behavior, depending on the nature of the "shear flow". Lecture Room D - SISSA Main Building ICTP pio@ictp.it

Europe/Rome The nonlinear Schroedinger equation appears in several physical or biological models and enjoys various interesting mathematical properties. In particular, this equation admits standing waves, i.e. solutions whose profile remains unchanged under the evolution in time. For the physical applications, it is essential to know the stability properties of waves with respect to perturbations. It is also important to understand the nature of any potential instability. The talk will start by a review of classical results on nonlinear Schroedinger equations and their standing waves. Then we will discuss stability and instability issues. Finally, we will present recent stability/instability results on a nonlinear Schroedinger equation perturbed by a Dirac potential. ICTP ICTP pio@ictp.it

Europe/Rome We predict a huge interference effect contributing to the conductance through large ultra-clean quantum dots of chaotic shape. When a double-dot structure is made such that the dots are the mirror-image of each other, constructive interference can make a tunnel barrier located on the symmetry axis effectively transparent. We show (via theoretical analysis and numerical simulation) that this effect can be orders of magnitude larger than the well-known universal conductance fluctuations and weak-localization (both less than a conductance quantum). A small magnetic field destroys the effect, massively reducing the double-dot conductance; thus a magnetic field detector is obtained, with a similar sensitivity to a SQUID, but requiring no superconductors.

Europe/Rome We determine the local density of states (LDOS) of one-dimensional incommensurate charge density wave (CDW) states in the presence of a strong impurity potential, which is modeled by a boundary. We find that the CDW gets pinned at the impurity, which results in a singularity in the Fourier transform of the LDOS at momentum 2k_F. At energies above the spin gap we observe dispersing features associated with the spin and charge degrees of freedom respectively. In the presence of an impurity magnetic field we observe the formation of a bound state localized at the impurity. All of our results carry over to the case of 1D Mott insulators by exchanging the roles of spin and charge degrees of freedom. We discuss the implications of our result for scanning tunneling microscopy experiments on spin-gap systems such as two-leg ladder cuprates. ICTP ICTP pio@ictp.it

In this class spin current is transferred by electron-hole pairs. Further, we consider a three-dimensional realization of class C. In the last part of the talk, we discuss application of the generalized Chalker-Coddington network model to the quantum spin Hall effect in graphene, which differs significantly from class C.

Europe/Rome The sliding of contacting surfaces is a formidable problem with impact in many areas, ranging from atomic to tectonic in scale. In several cases it can result in steady sliding or periodic stick-slip motion, but often displays an intermittent and erratic nature, for which effective descriptions are lacking. In order to investigate this kind of dynamics we have set up an experiment in which a rigid plate engages in stick-slip shear motion on a granular bed. In order to describe the resulting motion we have adopted an unusual approach which is not deterministic in nature (as opposed to, e.g. Burridge-Knopoff and Frenkel-Kontorova models), finding that the dynamics can be accurately described in a quantitative way by a simple stochastic equation, in which the resulting force exerted by the medium on the plate performs a random walk. Further work on the statistical properties of friction in solid-on-solid systems and comparisons with other phenomena suggest that a large class of driven instabilities can be described in terms of similar general mechanisms. Preliminary results on variable height and shaken granular bed are presented. ICTP ICTP pio@ictp.it

The connections to condensed matter physics are particularly strong in the case of optical lattices, where ultra-cold atoms can simulate many known condensed matter phenomena with unprecedented control. In addition, ultra-cold atoms can reveal completely new phenomena which are not possible to realize in standard condensed-matter systems, since interactions, hopping, dimensionality, and temperatures can be fully controlled in the atomic systems.

I begin by stating the approximations made that map QCD to a sigma model - the theory of Goldstone modes - and ultimately to a RMT formulation. Various correlation functions in the relevant symmetry class can be computed either from the sigma model or RMT, and then compared to numerical solutions of QCD in that limiting regime. Recent developments include non-Hermitian RMT and complex eigenvalue spectra of the QCD Dirac operator. ICTP ICTP pio@ictp.it

Europe/Rome Due to the Pauli blocking of the intermediate states, the scattering matrix (or T matrix) of two fermionic atoms in a Fermi gas becomes different from that of two atoms in free space. We calculate the in-medium T matrix in ladder approximation and study its effects on the properties of the collective modes of a trapped gas in the normal-fluid phase. We introduce the in-medium interaction on both sides of the Boltzmann equation, namely in the calculation of the mean field and in the calculation of the collision rate. This allows us to explain the observed upward shift of the frequency of the quadrupole mode in the collisionless regime. By including the mean field, we also improve considerably the agreement with the measured temperature dependence of frequency and damping rate of the scissors mode, whereas the use of the in-medium cross section deteriorates the description, in agreement with previous work.

Europe/Rome The electrons and holes in a graphene sheet behave very much like a relativistic liquid. As a consequence, the properties of thermo-electric transport of this fluid of interacting Dirac fermions are rather peculiar. At small doping and high temperatures, graphene exhibits many signatures of a quantum critical system: the inelastic scattering rate is set only by the temperature, and the conductivity assumes a nearly universal value, solely due to electron-hole friction. In this regime we find pronounced deviations from standard Fermi liquid behavior and a peculiar collective cyclotron resonance in the frequency dependent response. Some of these results have been anticipated by a relativistic hydrodynamic theory, and are fully confirmed by Boltzmann transport theory for weak coupling. Most interestingly, similar results are also found in the case of certain strong coupled liquids which can be solved exactly by the AdS-CFT correspondence. Moreover, in that context it is interesting that undoped graphene turns out to be a nearly ideal fluid with an anomalously small electronic viscosity, very similar to recent observations in the ultra-relativistic quark gluon plasma. I will also discuss possible consequences of the low viscosity for electronic transport in clean graphene. ICTP ICTP pio@ictp.it

Europe/Rome Recent experiments with ultracold atomic gases have triggered a great deal of interest in some fundamental aspects of the non-equilibrium dynamics of strongly correlated quantum systems. In particular, they raised an intense discussion on the general relation between system integrability and thermalization in the long-time dynamics of such systems. Instead of focusing on the asymptotic values of significant observables, we take a rather different perspective and study the dependence of the intrinsic dynamical time-scale on the initial state. We do this by considering the quantum Ising chain: we drive it out-of-equilibrium by abruptly quenching the transverse field. We focus on the onsite autocorrelation function of the order parameter, extracting the phase coherence time from its asymptotic decay. This phase coherence time is shown to be determined only by the final Hamiltonian gap, and an effective temperature which depends on the energy of the initial state after the quench. Moreover, the dependence of the coherence time on the effective temperature fairly agrees with that obtained in thermal equilibrium as a function of the equilibrium temperature. These results pertain to the Ising universality class, while the integrability of the model seems not to be crucial. SISSA Main Building - Room D ICTP pio@ictp.it

Europe/Rome We numerically study the adiabatic quantum dynamics of an anisotropic spin-1 XY chain across a second order quantum phase transition. The system is driven out of equilibrium by performing a quench on the uniaxial single-spin anisotropy, that is supposed to vary linearly in time. We focus on the behavior of the excess energy, which quantifies the loss of adiabaticity of the system during the evolution. For small system sizes only the ground state and the first excited state effectively participate in the evolution, so the dynamics can be explained in terms of a Landau-Zener model, which describes an avoided level crossing between two levels. For sufficiently large system sizes, the excess energy after the quench admits a non trivial scaling behavior that is not predictable by standard Kibble-Zurek arguments for isolated critical points or extended critical regions. This emerges from a competing effect of many accessible low-lying excited states, inside the whole continuous line of critical points. ICTP ICTP pio@ictp.it

Europe/Rome Alongside the effort underway to build quantum computers, it is important to better understand which classes of problems they will find easy and which others even they will find intractable. Inspired by the success of the statistical study of classical constraint optimization problems, we study random ensembles of the QMA$_1$- complete quantum satisfiability (QSAT) problem introduced by Bravyi. QSAT appropriately generalizes the NP-complete classical satisfiability (SAT) problem. We show that, as the density of clauses/projectors is varied, the ensembles exhibit quantum phase transitions between phases that are satisfiable and unsatisfiable. Remarkably, almost all instances of QSAT for any hypergraph exhibit the same dimension of the satisfying manifold. This establishes the random QSAT decision problem as equivalent to a, potentially new, graph theoretic problem and that the hardest typical instances are likely to be localized in a bounded range of clause density.

Europe/Rome Hawking radiation in black holes is the most famous and elusive prediction of Quantum Field Theory in curved spacetime, but so far no experiment is confirming its existence. More fundamental than the theory it has been first derived, Hawking radiation has been extended to any system able to reproduce the geometrical features of a forming black hole specetime: for example in supersonic flowing fluids the sound gets trapped exactly as light in a black hole. Such supersonic flow configurations are called "acoustic black holes" and can be used as laboratory to test gravitational effects otherwise undetectable (as Hawking radiation). It has been recently proposed how a clear signature of the presence of Hawking radiation in acoustic black holes appears in the density correlation pattern, analytically obtained using the formal analogy between gravitation and hydrodynamics, and numerically confirmed in an analysis able to take into account the full microscopic structure of the system. In this seminar the main features of the analogy between gravitation and hydrodynamics are reviewed. Then the peculiar correlation pattern associated to Hawking radiation is showed, and its important role to reveal it in near future experiments is underlined.

Europe/Rome The Levi curvatures of a real hypersurfaces of C^{n+1} are related to the Levi form the way the usual Mean or Gauss curvatures are related to the real Hessian form. They were implicitly introduced by Bedford and Gaveau in 1978, and more explicitly, in the case n=1, by Tomassini in 1988. Later on, Montanari and Lanconelli extended these notions to any dimension, following the lines of the works by Caffarelli, Nirenberg and Spruck on the real Monge-Ampere equations. Montanari and Lanconelli showed that, for hypersurface graphs on real functions, the Levi curvatures can be expressed in terms of second order fully nonlinear PDO's with an underlying sub-Riemannian structure. The properties of these structures allowed one to obtain: 1) A strong comparison principle for hypersurfaces having the same Levi curvatures; 2) Isoperimetric inequalities; 3) Alexandrov-type sphere theorems; 4) Existence theorems of Lipschitz-continuous viscosity solutions to the prescribed Levi-curvature problems 5) (only for n=1) Smoothness of the Lipschitz-continuous viscosity solutions. The results in 3) and 5) only give partial answers to problems which are still largely open. ICTP ICTP pio@ictp.it

Europe/Rome It is well-known that certain matrix solutions of the braid or Yang-Baxter equations lead to braided categories, knot invariants, quantum groups and other important constructions. However, these equations are also very interesting at the level of set maps $r:X\times X\to X\times X,$ where X is a set and r is a bijection, a line of study proposed by Drinfeld. Solutions extend linearly to very special linear solutions but also lead to a great deal of combinatorics, and to algebras with very nice algebraic and homological properties including those relating to Artin-Schelter regularity, Koszulity, being a PBW Noetherian domain, and the existence of noncommutative Groebner bases. In this talk I will examine solutions mainly from the point of view of finite permutation groups: a solution gives rise to a map from X to the symmetric group $Sym(X)$ on X satisfying certain conditions. Our results include many new constructions based on strong twisted union and wreath product, with an investigation of retracts and the multipermutation level and the solvable length of the groups defined by the solutions; and new results about decompositions and factorisations of the groups defined by invariant subsets of the solution. This talk is based on a joint work with Peter Cameron. ICTP ICTP pio@ictp.it

Europe/Rome Previous TTAs on the seasonal predictability in tropical regions have been successful to initiate seasonal prediction researches and contributed to application in the developing countries. Also, targeting research and operational groups were highly appreciated by both sides and appeared to contribute efficient capacity building of seasonal prediction activities in developing countries. The experience of several TTAs suggested that two aspects of seasonal prediction are still required to be addressed for TTA to be more fruitful. Many operational groups, even though they are producing forecast, showed a lack of fundamental knowledge of the predictability of climate system such as initial error growth, ensemble prediction, and boundary forced signal versus noise, etc. This lack of basic knowledge hindered understanding of practical applications and its further development. Therefore, one major theme of this TTA will be providing dedicated lessons on the theoretical and fundamental aspects of climate predictability. On the other hand, it is also necessary to keep aiming practical usefulness of seasonal prediction because it has immediate social needs. Recently, researches and applications of the seasonal prediction expand its horizon into different spatial and temporal scale, partly because of obtaining higher practical utility. In particular, climate variability within a season is a state-of-art research area with high social value in planning agricultural, hydrological activities. As an advanced continuation of previous TTA on the seasonal predictability, applications on the intraseasonal predictability by the statistical approach will be another focus in this TTA. For both themes, series of laboratory experiment will be carried on using simple dynamical models, sophisticated GCM outputs, as well as statistical methods with observation dataset. Therefore, the 2009 TTA aims are the following; 1. Provide dedicated lessons on fundamental knowledge of predictability of weather and climate system 2. Provide an updated overview on current research on the seasonal predictability 3. Support knowledge on the intraseasonal variability and opportunity to develop simple prediction scheme through the laboratory sessions. 4. Co-ordinate co-operation between the research and operational groups of the developing countries based on the laboratory projects. Trieste - Italy ICTP pio@ictp.it

Europe/Rome We explain the construction of a smooth codimension-one foliation on the 5-sphere in which every leaf is a symplectic four-manifold and such that the symplectic structure varies smoothly. The construction implies the existence of a complete regular Poisson structure on the five-sphere. Apart from some spheres which can be foliated by Riemann surfaces (this foliations are orientable and therefore symplectic) this example provides the only example of a regular Poisson structure on a sphere. This is joint work with Pablo Suarez (CIMAT, Mexico). ICTP ICTP pio@ictp.it

Europe/Rome PURPOSE AND NATURE Investigations in Plasma Physics span a vast array of intellectually exciting areas; from deep mathematical structures to state of the art technology. This interdisciplinary branch of physics (fusion, space-astrophysics, cosmology, industry etc.), overlaps significantly with many fields, such as condensed matter physics, nonlinear dynamical systems, high energy density environments and particle physics, and is continually evolving, conceptually as well as methodologically. The Summer College will be an attempt to bring both the traditional and emerging aspects of this field to an audience from developing countries. Topics to be covered include plasma waves, instabilities and heating, charge particle acceleration by strong fields, turbulence and self-organization at multi-scales, strong coupling of flows and fields, coherent nonlinear structures, non-thermal particle and heat transport processes, and vortex theory. Newly developed energy-related applications will also be discussed. An important aim of the college is to bring together plasma physicists working in different areas for the purpose of reviewing and discussing the present state of the art of collective nonlinear interactions in plasmas. The Summer College shall be interactive. Input from participants from developing countries will be highly welcome and they will have the opportunity of interacting among themselves as well as with other senior scientists/visitors. PROGRAMME The Summer College has a strong pedagogical component. The lectures will be an admixture of tutorials, reviews, and presentation of recent research. Active collaboration will be encouraged through classroom teaching and closely interacting working groups. It is hoped that, as in previous years, many participants will contribute to the poster sessions, and develop long-term working relations with the college lecturers and other participants.

Europe/Rome Double-layer structures, consisting of two parallel quantum wells separated by a potential barrier, are an important class of nanoscale electronic devices. Each layer hosts a quasi-two-dimensional electron gas and electrons interact across the barrier via Coulomb interaction. The combined action of the spin and pseudo-spin (associated with the layer index) degrees of freedom creates new phases in these bilayers where the spin and many-body interaction effects play a critical role. When an electric current is driven in one (active) layer of the bi-layer, the inter-layer Coulomb interaction causes charge accumulation in the other (passive) layer. This phenomenon, known as Coulomb drag, is of fundamental interest as a probe of electron correlations. Another effect of great interest is the Spin Hall Effect, the generation of spin accumulation by an ordinary electric current. The spin Hall effect is due to spin-orbit interaction and SOI and has been a subject of vigorous research both in semiconductors and metals in recent years not only because of its theoretical subtlety but also as a potential source of spin polarized currents. Lately, we have predicted and analyzed theoretically a new effect in bi-layers, which combines the interesting features of spin Hall effect and Coulomb drag. We call it Spin Hall Drag. SHD consists in the generation of spin accumulation across the passive layer by an electric current flowing along the other layer. Besides being a striking example of an effect that depends simultaneously on Coulomb interactions and spin-orbit coupling, the SHD has several unexpected and non-trivial features. It occurs in the absence of a current in the passive layer and, as we have shown, it is predominantly caused by a subtle effect known as side-jump in electron-electron collisions. This is at variance with the ordinary spin Hall effect, which, for electrons in GaAs, is dominated by an effect known as skew-scattering. We have shown that the skew-scattering and the side-jump contributions (considered for the first time in a context of electron- electron scattering) are separated by different temperature dependences at low temperature T, with the former vanishing much faster than the latter (T 3 vs T 2). Our calculations indicate that the induced spin accumulation is large enough to be detected in optical rotation experiments. ICTP ICTP pio@ictp.it

Europe/Rome Frictional motion plays a central role in diverse systems and phenomena that span vast ranges of scales, from the nanometer contacts inherent in micro- and nanomachines and biological molecular motors to the geophysical scales characteristic for earthquakes. Despite the practical and fundamental importance of friction and the growing efforts in the field, many key aspects of dynamics of friction are still not well understood. One of the main difficulties in understanding and predicting frictional response is the complexity of highly non-equilibrium processes going on in any tribological contact which include detachment and re-attachment of multiple microscopic contacts (bonds) between the surfaces in relative motion while still in contact. In this lecture I will discuss microscopic models which establish relationships between the dynamics of formation and rupture of individual contacts and frictional phenomena. First, I will focus on dynamics of nanoscale friction studied in friction force microscopy experiments. In this case we found that experimentally observed velocity and temperature dependencies of friction can be rationalized by explicitly considering the influence of temperature on the formation and rupturing of microscopic contacts. Then, dynamics of cracklike processes that occur at the interface between two macroscopic blocks prior to the onset of frictional motion will be discussed. In agreement with experimental observations, the proposed model demonstrates that the onset of sliding is preceded by well-defined detachment fronts initiated at the slider trailing edge and extended across the slider over limited lengths smaller than the overall length of the slider. We found that three different types of detachment fronts may play a role in the onset of sliding: (i) Rayleigh (surface sound) fronts, (ii) slow detachment fronts, and (iii) fast fronts. The important consequence of the precursor dynamics is that before the transition to overall sliding occurs, the initially uniform, unstressed slider is already transformed into a highly nonuniform, stressed state. Our model allows to explain experimental observations and predicts the effect of material properties on dynamics of transition to sliding. ICTP ICTP pio@ictp.it

Europe/Rome A brief overview of universal equations, which govern the propagation of nonlinear waves in various physical media (both classical - such as optical fibers - and macroscopic quantum media, such as Bose-Einsten condensates, BECs), will be given. The survey will include the nonlinear Schroedinger (NLS)/Gross-Pitaevskii equations, the sine-Gordon (SG) equation, the Korteweg - de Vries (KdV) equation, the Kadomtsev - Petviashvili (KP) equations, and some others (the KP equations are two-dimensional models). All the above-mentioned equations, in their ideal form, share the fascinating property of the exact integrability, by means of a mathematical technique known as "the inverse-scattering transform". Not only are these equations ubiquitous and universal, but also their fundamental solutions - first of all, solitons, i.e., solitary waves - play a profoundly important role in all physical settings to which the model equations apply. Solitons have been predicted in a great variety of physical systems, and one-dimensional solitons were observed and/or created experimentally in nonlinear optics, BEC, long Josephson junctions (superconductivity), fluid flows, plasmas, etc. A great challenge to the experiment is to produce stable two- and three-dimensional solitons.

Europe/Rome A quantum quench is a rapid change in time of a control parameter in the Hamiltonian describing a quantum, correlated many-body system. The physics of this paradigmatic non-equilibrium process, which has been realized recently in the context of cold atoms, is of particular interest in quantum critical systems where concrete dynamical manifestations of universality can be studied. In this talk I will discuss two fundamental ways to characterize these processes, by either looking at the statistics of basic thermodynamic variables or at the asymptotics of correlators. I will first elucidate the connection between a classic problem in condensed matter physics, the Fermi edge singularity, the statistics of the work done in a quantum quench, and quantum Jarzynski equalities. Using this connection, I will discuss results for the statistics of the work in a variety of systems, such as the quantum Ising chain, the Dicke model and quantum impurities. I will show that quantum criticality manifests itself in the emergence of interesting edge singularities in the statistics of the work and discuss their universality. Similarly, I will discuss how the critical properties are encoded in the asymptotics of non-equilibrium correlators. ICTP ICTP pio@ictp.it

Optical transitions (between Landau levels) in HgTe quantum wells are analyzed. We find selection rules which we functionalize to optically manipulate edge state transport. [1] In the absence of magnetic fields, the ballistic transport through HgTe quantum wells in the so-called inverted regime is believed to be dominated by edge state transport. The existence of these edge states (at zero magnetic field) is one of the hallmarks of topological insulators. We show that transport through the gapped bulk via evanescent modes can in general not be neglected in ballistic HgTe quantum wells. [1] M.J. Schmidt, E.G. Novik, M. Kindermann, and B.

Europe/Rome JOINT ICTP/SISSA STATISTICAL PHYSICS SEMINAR Within the framework of a simple model, we are able to study the overall performance of a given informational network, depending on its uptaking as well as on the level of traffic control. Simple enough to get analytical results, it still shows a very rich phenomenology, presenting continuous, discontinuous as well as hybrid phase transitions between a free-flow phase and a congested phase, critical points and different scaling behaviors in the system size. We find that traffic control improves global performance, enlarging the free-flow region in parameter space only in heterogeneous networks. Traffic control introduces non-linear effects and, beyond a critical strength, may trigger the appearance of a congested phase in a discontinuous manner. The model also reproduces the cross-over in the scaling of traffic fluctuations empirically observed in the Internet.

Europe/Rome In this talk, I will discuss unconventional superfluid states of various bosonic systems and present benchmark calculations for the ground state and finite temperature phase diagrams. The method of study is based on quantum Monte Carlo simulations by the Worm algorithm. The two qualitatively different systems to be discussed are: i) superfluidity of lower dimensional objects, i.e. dislocations and defects, embedded in solid structures both in optical lattices and in realistic systems such as 4-He. ii) the two-component Bose-Hubbard model. Bosonic optical lattice systems are also interesting for studies of quantum magnetism where under certain conditions they can be mapped onto various spin Hamiltonians. On the other hand, superfluid dislocations in 4-He are an important subject for their relevance to supersolid behavior observed in solid 4-He. ICTP ICTP pio@ictp.it

Europe/Rome Because of their very small carrier density, bismuth and graphite allow to attain the quantum limit in a bulk metal with available magnetic fields. The fate of a three-dimensional electron gas pushed to this ultra-quantum regime remains an open question. Recent measurements of the Nernst effect in graphite and in graphene combined to what was reported in bulk bismuth a few years ago, and in two-dimensional electron systems a decade earlier, permits to draw a striking correlation between the field profile of the Nernst response and dimensionality. When a Landau level intersects the Fermi level, the Nernst signal peaks in three-dimensional systems and vanishes in two-dimensional systems. We argue that this qualitative difference is a signature of a topological phase transition exclusive to three-dimensional systems. Beyond the quantum limit, when all carriers are confined to the first Landau level, Nernst effect in bismuth detects field scales, which are not expected in the one-particle picture. The field profile of these anomalies points to a bulk origin. According to our recent angular-dependent Nernst measurements, the band picture is quite successful in explaining the complex electronic spectrum of bismuth up to 9 T, but is inadequate as the quantum limit is crossed. In particular, in the vicinity of 40 T, that is more than four times the quantum limit, large anomalies in all transport properties point to an enigmatic reorganization of bulk electrons. Unexpectedly, this electronic instability leads to an enhanced conductivity and a better metallicity. ICTP ICTP pio@ictp.it

Europe/Rome Critical phenomena and quantum phase transitions are paradigmatic concepts in modern condensed matter physics. A central example in the field of mesoscopic physics is the localization-delocalization (metal-insulator) quantum phase transition driven by disorder -- the Anderson transition. Although the notion of localization has appeared half a century ago, this field is still full of surprising new developments. In this talk, I will discuss novel materials---graphene and topological insulators---where the charge carriers have a character of 2D Dirac fermions. A non-trivial topological nature of the corresponding theories leads to remarkable physical consequences. In graphene, the charge carriers turn out to be topologically protected from Anderson localization, as long as the intervalley scattering can be neglected. A similar phenomenon takes place for surface modes of a 3D topological insulator. Furthermore, we show that, in the latter system, the Coulomb interaction leads to emergence of a quantum critical state. Remarkably, the interaction-induced critical state emerges on the surface of a three-dimensional topological insulator without any adjustable parameters. This ``self-organized quantum criticality'' is a novel concept in the field of interacting disordered systems. Finally, we predict a quantum spin-Hall transition between the normal and topological insulator phases in 2D that occurs via a similar (or identical) quantum critical point. ICTP ICTP pio@ictp.it

Europe/Rome Certain strongly disordered superconducting films, when driven insulating by reducing thickness or by a small perpendicular magnetic field, are believed to maintain a strong pairing of electrons into localized Cooper pairs, the phase transition to an insulator merely signaling the loss of phase coherence across the sample. The ensuing bosonic insulator has a variety of very peculiar properties: empirically, it is found to exhibit a simply activated resistance of purely electronic nature. I will analyze the new question of the spectral properties of the disordered interacting system across the phase transition in the light of the phenomenon of localization in Fock space. This analysis leads to a possible explanation of the above-mentioned properties in terms of localized Cooper pairs which couple only very weakly to phonons. Open and controversial issues will be discussed. REFERENCES: M. Müller, arXiv:0909.2260 I.L. Aleiner, B.L. Altshuler, G.V. Shlyapnikov, arXiv:0910.4534 ICTP ICTP pio@ictp.it

Europe/Rome Mean field glassy system have been the subject of much studies over the last decades. They arise as mean field models for the glass transition, but also as models for complex systems and optimization problems. Their thermodynamics properties can be solve using the replica, or the cavity method. In this talk, I will introduce a generalization of the cavity method that allows to follow Gibbs states in mean field systems when an external parameter, e.g. the temperature, is tuned. The method thus yields a "static" way to study long time "dynamics" in mean field models of glass formers, spin glasses, or random constraint satisfaction problems. In optimization problems the method gives limits for the performance of the simulated annealing algorithm. It also gives new results on the stability and the marginality of the non-equilibrium states, on the spinodal point upon heating, and allow to demonstrate the presence of temperature chaos.

Europe/Rome Due to recent experimental achievements with trapped ultracold atoms, the properties of the 1D non-relativistic Bose gas are of great interest. In many experimental setups the behaviour of the particles is very well described by the Lieb-Liniger model which in many aspects can be regarded as a theoretical benchmark in the research of integrable models. In spite of its integrability, calculating correlation functions in the model is notoriously difficult. In the talk I will propose a novel approach to compute expectation values and other physical quantities in the Lieb-Liniger model. The method is based on the fact that in the repulsive case the S-matrix, the Lagrangian and the operators can be obtained from a certain non-relativistic limit of the sinh-Gordon model. This observation allows us to compute expectation values both at zero and finite temperature. Among other results, I present the computation of the three-body correlation function at finite temperature, which is closely related to the recombination rate of the gas.

Europe/Rome I present a quantitative approach to interactive learning and adaptive behavior, which integrates model- and decision-making into one theoretical framework. This approach follows simple principles by requiring that the observers behavior and the observers internal representation of the world should result in maximal predictive power at minimal complexity. Classes of optimal action policies and of optimal models can be derived from an objective function that reflects this trade-off between prediction and complexity. The resulting optimal models then summarize, at different levels of abstraction, the process causal organization in the presence of the feedback due to the learners actions. A fundamental consequence of the proposed principle is that the optimal action policies have the emerging property that they balance exploration and control. Interestingly, the explorative component is present also in the absence of policy randomness, i.e. in the optimal deterministic behavior. Exploration is therefore not the same as policy randomization. This is a direct result of requiring maximal predictive power in the presence of feedback. It stands in contrast to, for example, Boltzmann exploration, which is frequently used in Reinforcement Learning (RL). Time permitting, I will discuss what happens when one includes explicit goals and rewards into the theory, as is popular in RL. Lecture Room D - SISSA Main Building ICTP pio@ictp.it

Europe/Rome Using the mapping from the Fokker-Planck description of classical stochastic dynamics into a quantum Hamiltonian, we argue that a dynamical glass transition can be given a precise definition in terms of a static (equilibrium) quantum phase transition. This transition is characterized by a massive collapse of the excited states, leading to a divergent static quantum susceptibility throughout the glassy phase, which directly relates to a non-vanishing Edwards-Anderson order parameter. The quantum mechanical language allows to search for off-diagonal order parameters to detect the classical ‘dynamic order’ using transverse bases – an approach that corresponds to non-static observables in the original classical language. Even in the absence of a local order parameter, the transition can be detected via quantum fidelity measures on the ground state wavefunction, which we show to translate directly into a singularity in the heat capacity of the classical system.

Europe/Rome Graphene is a new material consisting of a one-atom-thick layer of graphite. It has been discovered only a few years ago and since its discovery it has shown to possess many unique and fascinating properties. These properties are a consequence of the fact that electrons in graphene effectively behave as massless relativistic electrons, whose dynamics is described by the two-dimensional Dirac equation. In this talk I will first introduce the field, by explaining in some detail how the electronic properties of graphene originate, how they manifest themselves in the experiments, and how the experiments are actually done. I will then move to discuss more specific topics that we have investigated during the past few years. These include phase coherent transport of electrons (Aharonov-Bohm effect, weak-localization, Josephson supercurrent), finite conductivity at the charge neutrality point, and gate-tunable band structure. Taken together, these examples make clear that graphene (single-layers as well as materials consisting of a small number of layers) indeed is a unique material system, in which the discovery of new physical phenomena can be expected, and which could be of use in future electronic applications.

Europe/Rome Nanophysics has emerged in the last decade as a new distinct sub-branch of physics. It deals with the fundamental physical phenomena that take place at the nanoscale and that find application in the rapidly developing field of nanotechnology. Theoretical and computational aspects of Nanophysics will be covered during this activity. The school is intended for young promising scientists (students and researchers) from Vietnam, Laos and Cambodia, and other South-East Asian countries. Topics: - Introduction to nanophysics - Physics of carbon nanotubes - Physics of graphene and graphene nanoribbons - Mesosocopic systems - Quantum dots - Nanowires, nanoclusters and nanostructures on surfaces - Computational approaches based on: o Density functional theory o Molecular dynamics === INVITED LECTURERS: I.
