Europe/Rome We study the number of clusters in 2d critical percolation, NΓ , which intersect a given subset of bonds, Γ. In the simplest case, when Γ is a simple closed curve, NΓ is related to the entanglement entropy of the critical diluted quantum Ising model, in which Γ represents the boundary between the subsystem and the environment. Due to corners in Γ there are universal logarithmic corrections to NΓ , which are calculated in the continuum limit through conformal invariance making use of the Cardy-Peschel formula. The exact formulae are confirmed by large scale Monte Carlo simulations. These results are extended to anisotropic percolation where they confirm a result of discrete holomorphicity. I. A. Kovács, F.

Europe/Rome Abstract: The next few years will bring a wealth of new information about the primordial cosmological fluctuations. In this talk, I will discuss how observable non-Gaussianities and gravitational wave signals encode the physics of the early universe. First I will discuss signatures of global symmetries in the early universe, arguing that even the simplest slow roll inflation models can lead to observable non-Gaussianity and primordial gravity waves. Next, I will consider more generally the possibility to probe how the inflaton couples to radiation. ICTP ICTP pio@ictp.it

Europe/Rome A 2D model of three-valued discrete-strain pseudospins S (r)=0, +1,-1 is studied in Monte Carlo simulations, under systematic temperature quenches, without extrinsic disorder [1]. The reduced model is from Landau minima of a continuum-strain free energy of the square-rectangle martensitic transition. The pseudospins interact via a power-law anisotropic potential obtained from the St Venant Compatibility constraint. The same procedure yields pseudospin models for other 2D and 3D transitions [2]. After a temperature quench, dilute martensitic seeds in an austenite background, induce sequential domain-wall phases of a 'vapour' of a martensite droplet in austenite; a 'liquid' of disordered martensite domain walls; and a ‘crystal’ of oriented-wall twins. The evolution is tracked through Temperature-Time –Transformation (TTT) curves, with time scales for conversion to martensite t_m (T); and Compatibility-driven domain-wall orientation, t_C (T). Depending on elastic constants, t_m (T) can either be thermally activated and slow, as in 'isothermal' martensites; or non-activated and explosive, as in 'athermal' martensites below a martensite start temperature ~ T_1. For quenching to above such a temperature, we find (generically) a delay tail, that rises towards a temperature T=T_4 > T_1. This is identified with the puzzling delay tail in t_m (T) found by Kakeshita [3]. The mean time shows glass-like Vogel-Fulcher behaviour, t_m ~ exp [ 1/( T_4 - T)], and distributions are log-normal [1]. The times are insensitive to the Hamiltonian energy scale E_0, and are attributed to entropy barriers that vanish/ diverge at T_1 and T_4. The conversion delays are from searches in Fourier space on constant-energy surfaces, for rare energy-lowering pathways. The 'vapour' phase structure-factor peak has to find pathways to distort and roll into a small anisotropic 'golf hole'; to be then guided by a 'funnel' into a 'liquid' phase; and finally symmetry-broken, to a 'crystal' phase. A time- dependent effective temperature re-equilibrates to the bath temperature. The entropic golf-hole, and energetic funnel, are concepts from protein folding [4]. [1] N. Shankaraiah, K.P.N.

Europe/Rome The integration of various types of genomic data into predictive models of biological networks is one of the main challenges currently faced by computational biology. Constraint-based models in particular play a key role in the attempt to obtain a quantitative understanding of cellular metabolism at genome scale. In essence, their goal is to frame the metabolic capabilities of an organism based on minimal assumptions that describe the steady states of the underlying reaction network via suitable stoichiometric constraints, specifically mass balance and energy balance (i.e. thermodynamic feasibility). The implementation of these requirements to generate viable configurations of reaction fluxes and/or to test given flux profiles for thermodynamic feasibility can however prove to be computationally intensive. We propose here a fast and scalable stoichiometry-based method to explore the Gibbs energy landscape of a biochemical network at steady state. The method is applied to the problem of reconstructing the Gibbs energy landscape underlying metabolic activity in the human red blood cell, and to that of identifying and removing thermodynamically infeasible reaction cycles in the Escherichia coli metabolic network (iAF1260). In the former case, we produce consistent predictions for chemical potentials (or log-concentrations) of intracellular metabolites; in the latter, we identify a restricted set of loops (23 in total) in the periplasmic and cytoplasmic core as the origin of thermodynamic infeasibility in a large sample of flux configurations generated randomly and compatibly with the prior information available on reaction reversibility.

Europe/Rome Abstract. Very light axion-like particles (ALPs) with a two-photon vertex are predicted in many extensions of the Standard Model of particle physics. Depending on the actual value of their mass, ALPs can play an important role in cosmology, either as cold dark matter particles or as quintessential dark energy. The coupling with photons allows for ALP-photon mixing in external electromagnetic fields. This effect is exploited for direct searches of ALPs in laboratory experiments. The two-photon vertex would also induce the mixing with ALPs for photons emitted by distant astrophysical sources, and propagating in the large-scale cosmic magnetic fields. Indeed, different astrophysical puzzles would be naturally solved by conversions of cosmic photons into ALPs. Motivated by these intriguing hints, I will discuss how current and upcoming astrophysical experiments, ranging from the cosmic microwave background to the high-energy gamma-rays, could probe the elusive ALPs in a region of their parameter space not accessible by laboratory experiments.

Europe/Rome I will discuss finite volume matrix elements of local operators in integrable quantum field theories and present a conjecture relating finite and infinite volume form factors in the most general setting, i.e. including the case of form factors containing disconnected pieces in the presence of non-diagonal scattering. Specializing to the sine-Gordon model, finite volume multi-soliton form factors are compared to numerical data coming from a numerical renormalization group calculation in the truncated conformal space. I find excellent agreement between the two approaches, thus verifying both bootstrap for multi-soliton form factors and the theory linking finite and infinite volume matrix elements. Evaluation of the nontrivial multi-soliton form factors is achieved by a newly developed regularization scheme. SISSA, Santorio Building, Room 128 (1st Floor) ICTP pio@ictp.it

An order reduction method is used to eliminate the spurious solutions associated with higher order derivatives. Our exact (nonperturbative) solutions show that de Sitter spacetime is stable and a large time attractor. This extends some of the existing â€œno-hairâ€ results for de Sitter spacetime.

Europe/Rome The origin of the pseudogap is widely debated for cuprate superconductors. The main controversy concerns whether superconductivity and the pseudogap phase are competing with each other or are manifestations of the same phenomenon. In the latter case, pairing fluctuations would extend above the critical temperature (Tc) the effects of the pairing gap below Tc [1]. A contribution to settle this controversy can be obtained by ultracold fermions, which are free of the structural complications of cuprates and where only pairing fluctuations are present above Tc. In these systems, the inter-particle attraction can be varied by Fano-Feshbach resonances as to amplify the effects of pairing fluctuations. In this context, wave-vector resolved radio frequency spectroscopy data for an ultracold trapped Fermi gas are reported for several couplings at Tc, and analyzed by a pairing-fluctuation theory. We show that the non-Fermi-liquid behavior associated with the presence of a pseudogap coexists with a robust remnant Fermi surface over a wide coupling range, which sets the boundary of the pseudogap phase [2,3,4]. Moreover, the properties of the pseudogap phase obtained within the t-matrix approach are compared with the outcomes of recent quantum Monte Carlo (QMC) ab initio simulations [5,6]. Once the pseudogap has been characterized in ultracold fermions, we compare the temperature dependence of the spectral intensity suppression obtained within our theory with the one measured in cuprates by angular resolved photoemission spectroscopy (ARPES) [7].

Europe/Rome The study of an almost Ricci soliton was introduced in a recent paper due to Pigola, Rigoli, Rimoldi and Setti. This structure represents a generalization to Einstein metrics and Ricci soliton, they appear as special solutions of the Ricci flow. In this seminar we shall talk about two results. The first treats of the characterization of compact almost Ricci solitons , more precisely, in this work we find some structure equations for almost Ricci solitons which generalize the equivalent for Ricci solitons. As a consequence of these equations we derive an integral formula for the compact case which enables to show that a compact nontrivial almost Ricci soliton is isometric to a sphere, provided either it has constant scalar curvature or its associated vector eld is conformal. Next, we prove that any compact almost Ricci soliton with constant scalar curvature is isometric to a Euclidean sphere. As a consequence we obtain that every compact almost Ricci soliton with constant scalar curvature is gradient. ICTP ICTP pio@ictp.it

Europe/Rome Quantum many-body physics has traditionally been dominated by detailed investigations of equilibrium properties and low-energy excitations. In the last decade or so, motivated by novel experimental possibilities such as cold atoms, the study of quantum matter far from equilibrium has emerged as an important and exciting new field. I will start with a selection of new questions and phenomena that have appeared in the context of non-equilibrium evolution in isolated systems. I will end by focusing on a specific example, namely, the dynamics of composite objects in lattice systems. such as repulsively bound pairs, triplets and clusters. ICTP ICTP pio@ictp.it

Europe/Rome Abstract: We explore the dynamics of metric perturbations (gravitational waves) on the cosmological background in the theory with higher derivatives and semiclassical non-local corrections coming from massless conformal fields. It is shown, by means of analytical and numerical methods that there are no growing modes until the background has enegies of Planck order of magnitude. This result means, also, that there are good chances to construct renormalizable theory of quantum gravity which is unitary for the energies below Planck scale. ICTP ICTP pio@ictp.it

Europe/Rome For sensory networks, we determine the rate with which they acquire information about the changing external conditions. Comparing this rate with the thermodynamic entropy production that quantifies the cost of maintaining the network, we find that there is no universal bound restricting the rate of obtaining information to be less than this thermodynamic cost. These results are obtained within a general bipartite model consisting of a stochastically changing environment that affects the instantaneous transition rates within the system. Moreover, they are illustrated with a simple four-states model motivated by cellular sensing. On the technical level, we obtain an upper bound on the rate of mutual information analytically and calculate this rate with a numerical method that estimates the entropy of a time-series generated with a simulation.

Europe/Rome Abstract: There are three types - three "flavors" of neutrinos: electron, muon and tau. Enormous progress in neutrino physics was related to the discoveries of flavor oscillations and flavor conversion of neutrinos in matter. These discoveries allowed us to detrmine the neutrino mass parameters and mixing and to elaborate neutrino "flavor optics". I will describe recent developments in the field which include measurements of the 1-3 mixing, searches for new (flavorless) neutrinos, attempts to understand the origins of neutrino mass. I will outline possible future progress in the field. ICTP ICTP pio@ictp.it

Europe/Rome Recent experimental progress in the physics of ultracold atomic gases has revived the interest in the behavior of thermally isolated quantum statistical systems, especially after sudden changes (quenches) of their control parameters. Considering the quench as a thermodynamic transformation, it is natural to focus on the irreversible work done on the system, which is characterized by a certain probability distribution. By studying its large deviations, i.e., rare fluctuations of the work per unit volume, we establish a connection with the physics of a classical system confined in a film geometry. If the system is quenched close to a (quantum) critical point, both the edge singularity and the large deviations of the irreversible work acquire universal features dictated by the critical Casimir effect in the corresponding classical system. In systems of bosons, the statistics of the work may additionally display a transition which is analogous to the equilibrium Bose-Einstein condensation. ICTP ICTP pio@ictp.it

Europe/Rome Abstract: Gauge theories, such as the one describing strong interactions, contain string-like excitations. String theory describes the quantum dynamics of strings and it reduces to gravity at long distances. The simplest versions of string theory live in a ten dimensional spacetime. We will explain how these ten dimensional strings are intimately connected to the strings that appear in four dimensional gauge theories. The four dimensional gauge theory gives rise to a gravitational theory in a higher dimensional curved spacetime. The gravitational theory is simple to analyze when the four dimensional theory is strongly interacting. This provides a simple way of studying strongly coupled phenomena en quantum field theories. In addition, it can be used to describe black holes in a fully quantum mechanical fashion. ICTP ICTP pio@ictp.it

Europe/Rome Abstract: Several unexplained results from neutrino oscillation experiments and from cosmology have sparked renewed interest in extensions of the Standard Model containing light sterile neutrinos. In this talk, we first discuss the status of such models, we present results from a global fit to neutrino oscillation data, and we discuss the tension between different data sets. In the second part of the talk, we explore the possible implications that the existence of sterile neutrinos could have for dark matter searches. In particular, resonantly enhanced active-to-sterile oscillations can weaken limits on dark matter annihilation in the Sun. On the direct detection side, we show that models in which sterile neutrinos form part of a larger hidden sector can lead to interesting new signatures of solar sterile neutrinos scattering on electrons or nuclei. On the one hand, these signatures provide a new application for dark matter detectors, on the other hand they are not always easy to distinguish from dark matter scattering signals.

Europe/Rome Founded over a century ago, statistical mechanics (SM) for systems in thermal equilibrium has been so successful that, nowadays, it forms part of our physics core curriculum. On the other hand, most of "real life" phenomena occur under non-equilibrium conditions. Unfortunately, statistical mechanics for such systems is far from being well established. The goal of understanding complex collective behavior from simple microscopic rules (of evolution, say) remains elusive. As an example of the difficulties we face, consider predicting the existence of a tree from an appropriate collection of H,C,O,N,... atoms! Over the last two decades, an increasing number of condensed matter theorists are devoting their efforts to this frontier. After a brief summary of the crucial differences between text-book equilibrium SM and non-equilibrium SM, I will give a bird's-eye view of some key issues, ranging from the "fundamental" to (a small set of) the "applied." The methods used also span a wide spectrum, from "easy" computer simulations to sophisticated field theoretic techniques. These will be illustrated in the context of an overview of our work, as well as a simple Ising model coupled to two thermal baths. SISSA, Santorio Building, Room 5 (ground floor) ICTP pio@ictp.it

Europe/Rome The hard-disk model has exerted outstanding influence on computational physics and statistical mechanics. Decades ago, hard disks were the first system to be studied by Markov-chain Monte Carlo methods and by molecular dynamics. It was in hard disks, through numerical simulations, that a two-dimensional melting transition was first seen to occur even though such systems cannot develop long-range crystalline order. Analysis of the system was made difficult by the absence of adequate simulation methods. In recent years, we have developed a number of powerful Monte Carlo algorithms for hard disks and related systems. I will in particular show how the powerful event-chain Monte Carlo algorithm has allowed us to show that hard disks melt with a first-order transition from the liquid to the hexatic and a continuous transition from the hexatic to the solid. I will finish with discussions on the general theory of two-dimensional melting and on the generalizations of the event-chain algorithm. ICTP ICTP pio@ictp.it

Europe/Rome I will discuss the fundamental equivalence between thermodynamic inefficiency, measured by dissipation, and information processing inefficiency. The dynamics of any system responding to a stochastic environmental signal can be interpreted as computing an implicit model of the driving signal. The system’s state retains information about past environmental fluctuations, and a fraction of this information is predictive of future fluctuations. The remaining nonpredictive information reflects model complexity that does not improve predictive power, and thus represents the inefficiency of the model. We find that instantaneous nonpredictive information: 1) is proportional to the work dissipated due to environmental change; 2) provides a lower bound on the total dissipated work when summed over the length of a driving protocol; 3) augments the lower bound on heat generated due to information erasure (Landauer's principle). Our results hold far from thermodynamic equilibrium and are thus applicable to a wide range of systems, including biomolecular machines, and potential future nano computing devices. These results highlight a profound connection between the effective use of information and efficient thermodynamic operation: any system constructed to keep memory about its environment, and to operate with maximal energetic efficiency, has to be predictive. http://prl.aps.org/abstract/PRL/v109/i12/e120604 SISSA, Santorio Building, Room 128 (1st Floor) ICTP pio@ictp.it

Europe/Rome Non-linear sound is an extreme phenomenon typically observed in solids after violent explosions. But granular media are different. Right when they unjam, these fragile and disordered solids exhibit vanishing elastic moduli and sound speed, so that even tiny mechanical perturbations form supersonic shocks. Here, we perform simulations in which two-dimensional jammed granular packings are continuously compressed, and demonstrate that the resulting excitations are strongly nonlinear shocks, rather than linear waves. We capture the full dependence of the shock speed on pressure and compression speed by a surprisingly simple analytical model. We also treat shear shocks within a simplified viscoelastic model of nearly-isostatic random networks comprised of harmonic springs. In this case, anharmonicity does not originate locally from nonlinear interactions between particles, as in granular media; instead, it emerges from the global architecture of the network. As a result, the diverging width of the shear shocks bears a nonlinear signature of the diverging isostatic length associated with the loss of rigidity in these floppy networks.

Europe/Rome Abstract. Using holography we study the imaginary of the heavy quark anti-quark (dipole) potential in the anisotropic plasma at finite temperature. The anisotropic plasma is a deformation of N=4 SYM theory by adding a Theta-term depending on the anisotropy direction to the action. From gravity side the deformation can be thought as generated from a back-reacting number of D7 branes wrapping the internal 5-sphere and two of the spatial directions (transverse directions) in the space-time. The imaginary part of the potential creates a thermal width and by comparing the results with isotropic case we show that the thermal width in the anisotropic plasma is larger than the isotropic case. The thermal width is a function of the angle between the dipole and anisotropy direction and we show that the thermal width in anisotropy direction is larger than the thermal width in transverse direction.

Europe/Rome We experimentally study the transport process of ultracold fermionic atoms through a mesoscopic, quasi two-dimensional channel connecting macroscopic reservoirs. By observing the current response to a bias applied between the reservoirs, we directly access the resistance of the channel in a manner analogous to a solid state conduction measurement. The resistance is further controlled by a gate potential reducing the atomic density in the channel, like in a field effect transistor. In this setup, we study the flow of a strongly interacting Fermi gas, and observe a striking drop of resistance with increasing density in the channel, as expected at the onset of superfluidity. The resistance is compared to that of an ideal Fermi gas in the same geometry, which shows an order of magnitude larger resistance, originating from the contact resistance between the channel and the reservoirs. We extended this investigation to disordered superfluids and provide evidences for a disorder-induced breakdown of superfluidity. ICTP ICTP pio@ictp.it

Europe/Rome We discuss the formation of bound states made of two interacting atoms moving in a one dimensional (1D) quasi-periodic optical lattice. The underlying hamiltonian is the Aubry-André model with additional on-site interactions. We derive the quantum phase diagram for localization of both attractively and repulsively bound pairs. We calculate the pair binding energy and show analytically that its behavior as a function of the interaction strength depends crucially on the nature -extended, multifractal, localized- of the single-particle atomic states.

Europe/Rome Abstract: We address the problem of the conditions under which an endomorphism(non-invertible map) having a dense orbit ensures that a sufficiently close perturbed map also exhibits a dense orbit. In this context, we give sufficient conditions, which cover a large class of examples, for endomorphisms on the n-dimensional torus to be robustly transitive: the endomorphism must be volume expanding and any large connected arc must contain a point such that its future orbit belongs to an expanding region. (Joint work with E. Pujals) If we have enough time, I will show some ergodic properties for a generic subset of this class of maps. More concretely, the existence of interesting measures such as ergodic expanding invariant measures with full support and exhibiting exponential decay of correlations. (Joint work with V. Pinheiro and P.Varandas) Some examples will be shown. ICTP ICTP pio@ictp.it

Europe/Rome A substantial magnetodielectric effect is usually an indication of coupled magnetic and elastic order, such as is found in the multiferroics. However, here I will show that magnetism is not necessary to produce either a magnetoresistance or a magnetocapacitance when the material is inhomogeneous. From exact calculations and numerical simulations of metal-dielectric composites, I find a characteristic dielectric resonance that sensitively depends on magnetic field. I will discuss how this behaviour has already been observed experimentally in some materials. ICTP ICTP pio@ictp.it

Europe/Rome (This is the second of a series of approximately 4 lectures of 60 minutes). The subject of these lectures is enumerative geometry of curves on algebraic surfaces and its relation to Hilbert schemes of points, real algebraic geometry and tropical geometry. The generating function of the Euler numbers of Hilbert schemes of points on curves has been used by Pandharipande and Thomas to give a mathematical definition of Gopakumar-Vafa invariants, and by Kool-Shende-Thomas to give a proof of a conjecture of mine which describes the generating function of the numbers of δ-nodal singular curves in a linear system of dimension δ on any surface. Shende and me gave a conjectural refinement of this conjecture. Here the number of curves is replaced by a polynomial, whose meaning is still mysterious, but it can be seen to be related to tropical geometry and real algebraic geometry. In this series of lectures we want to explain this circle of ideas, and also use the opportunity to introduce a number of important concepts and techniques, generating functions, cobordism ring, localization, Severi degrees, Welschinger invariants, tropical geometry, Heisenberg algebra.

Europe/Rome Abstract: We consider a family of adapted complex structures on the cotangent bundle of a Lie group and find the BKS pairing relating the corresponding half-form quantisation. We show that the resulting bundle of quantum Hilbert spaces over the space of polarisations is flat. The vertical polarisation as a limit of complex polarisations yields the coherent state transform (or the Segal-Bargmann-Hall transform). We show that there is another limit of the complex polarisations that corresponds to the Peter-Weyl theorem. This is a joint work with W. Kirwin. ICTP ICTP pio@ictp.it

Europe/Rome I review the concept of ultra-cold atoms as universal quantum simulators for quantum many body systems, focusing on motivations, main targets and open problems. As a realistic example I then describe a setup of ultracold fermionic mixtures in optical lattices able to host superfluid phases with symmetry obtained by locking independent invariance groups of the normal state. Due to their peculiar symmetry, these phases can also show exotic soliton structures, as vortices with semi-integer flux and gapless non-Abelian Goldstone modes localized on them. The origin of the non-abelianity, the braiding properties, the mechanism and the consequences of fractionality for such vortices are discussed. The scenario proposed displays remarkable similarities to what arises in ultra-dense QCD matter, as in the core of some neutron stars. A discussion about the experimental detection of locked phases and non-abelian fractional vortices is as well provided. ICTP ICTP pio@ictp.it

Europe/Rome More than 10 years ago, it was realized that mean field glassy dynamics, with the emergence of aging and effective temperatures, can be understood as quasi-equilibrium exploration of configuration space. The formalization of this notion, only recently proposed, defines a Markov chain where short times are coarse grained, and subsequent configurations are chosen according to a constrained Boltzmann distribution. In mean field spin glasses, this pseudodynamic rule admits, in the long time limit, a description leading to glassy solutions identical to the ones corresponding to real (Langevin) dynamics. The treatment of the pseudodynamics through replicas unveils a longly suspected relation between replicas and the supersymmetry of the Langevin equation. The application of the formalism to liquids avoids the difficulties related to short time conservation laws, and allows to use equilibrium approximation schemes of liquid theory to study long time dynamics. The scheme is applied to a closure scheme of hierarchical equations recently proposed by Szamel and to liquids in the hypernetted chain (HNC) approximation. It is shown that the former case leads to the standard Mode Coupling Theory (MCT) equations of Gœtze, thus giving an interpretation of it. The second case also gives rise to MCT-like equations, but in a framework where, differently from MCT that requires the input of equilibrium structure factors, static equilibrium and dynamical quantities are computed in a unified consistent framework.

This will lead us to magnetic superatoms. I will also point out how a subtle interplay of crystal field effect and exchange coupling leads to enhanced stability for certain TM-alkaline earth clusters, and leads to new magnetic superatoms in this series. Time permitting, I will present some of our recent results on TM-doped aluminum clusters and will argue that aromaticity rather than shell models plays a role in these clusters.

Europe/Rome Recently, Coulomb drag measurements have been performed in graphene, usually in the presence of magnetic fields as well. In this work we calculate the magneto-drag and the Hall-drag resistivity at finite temperature for two graphene monolayers by solving the quantum kinetic equation. The presented theory is valid in the hydrodynamic regime, which is dominated by inelastic scattering. The microscopic formulation supports a phenomenological Drude-like picture which for large concentrations equals the usual Drude form, and for small concentration an effective two-band-Drude equation. Our theory allows for a qualitative description for arbitrary chemical potentials. An emphasis is put on the Hall-drag which is absent when derived from the standard Drude equation. We show that the Hall-drag vanishes along the line of opposite carrier concentration in the layers, but we also identify non trivial concentrations at which the Hall-drag vanishes.

Europe/Rome The talk will discuss the dynamics of circle maps (orientation-preserving circle homeomorphisms (o.p.c.h)). We will review the topological classification of these circle maps, namely the Poincare Classification and the Denjoy Theory. We will introduce the beautiful construction of the dynamical partition of the circle. We will review the connection between the concept of the Diophantine properties of the irrational rotation number of our map and the smooth classification of (sufficiently regular) circle maps (the so called "rigidity" theory), in the context of three important classes: diffeomorphisms, critical maps, and maps with a break point. For circle maps with a break point, we will discuss two recent results that were obtained in the rigidity theory of circle maps with a break point. The first main result is a proof that C^1 rigidity holds for circle maps with a break point for almost all irrational rotation numbers. This result is joint work with Kostya Khanin and Sasa Kocic. The second main result has to do with the family of fractional linear transformation (FLT) pairs. An FLT-pair T is a circle homeomorphism that consists of two branches each of which is an FLT. Such a map can be viewed as a circle map with two neighbouring break points lying on the same orbit. For this family, C^1 rigidity holds for all irrational rotation numbers without any restriction (the so-called "robust rigidity"). ICTP ICTP pio@ictp.it

Europe/Rome Abstract: Bertrand spacetimes (BSTs) are static, spherically symmetric solutions of Einstein's equations, that admit stable, closed orbits. Starting from the fact that to a good approximation, stars in the disc or halo regions of typical galaxies move in such orbits, we propose that, under certain physical assumptions, the dark matter distribution of some low surface brightness (LSB) galaxies can seed a particular class of BSTs. In the Newtonian limit, it is shown that for flat rotation curves, our proposal leads to an analytic prediction of the NFW dark matter profile. ICTP ICTP pio@ictp.it

Europe/Rome Abstract. The Dual Superconductor picture, proposed as a resolution for the prob- lem of Quark Confinement, predicts Flux Tubes connecting quarks. Evidence for such flux tubes in QCD has been unambiguously provided by Lattice Gauge Simulations. An algorithmic breakthrough by Luscher and Weisz permitted very accurate studies of the flux tube which showed that the sub- dominant term in ground state energy was characterstic of Bosonic Strings, the original candidates for explaining strong interactions. Pushan Majumdar and myself carried out massive simulations using the Luscher-Weisz algorithm. We showed that even the next two higher order terms are exactly what is expected of a free bosonic string. Peter Matlock and myself subsequently proved this result analytically using the idea of effective string theories. I shall conclude by briefly reviewing the status of even higher order corrections as well as some implications of all these results. ICTP ICTP pio@ictp.it

Europe/Rome Abstract: The SuperCool inflation has the virtue of working "Naturally" at TeV scales and even much lower, which opens the possibility of using collider physics to probe inflation. In addition, the model introduces a new mechanism to end Old inflation. The Universe starts off hot and trapped in a false vacuum. The Universe supercools and inflates solving the horizon and flatness problems. The inflaton couples to a set of QCD like fermions. When the fermions' non-Abelian gauge group freezes, the Yukawa terms generate a tadpole for the inflaton, which removes the barrier. Inflation ends, and the Universe rapidly reheats. The model also can generate the necessary perturbations for inflation and can satisfy constraints from Plank. ICTP ICTP pio@ictp.it

Europe/Rome Abstract I will discuss the global phase diagram of the disordered Bose-Hubbard model in all dimensions controlled by the theorem of inclusions. In 1D, in the regime when strong disorder is more relevant than field quantization the superfluid--to--Bose-glass criticality is preceded by the prolonged logarithmically slow classical-field renormalization flow of the superfluid stiffness at mesoscopic scales. With the system compressibility remaining constant, the quantum nature of the system manifests itself only in the renormalization of dilute weak links. The transition point is still controlled by the proliferation of the instanton--anti-instanton pairs when the Luttinger liquid parameter equals 3/2, in accordance with the universal quantum scenario.

With current electronic-structure theory, quantitative analyses and predictions of hitherto unknown properties and functions of materials (including nanostructures, clusters, (bio)molecules) are possible. The finding of improved or even novel functional materials is critical to solve key issues of our society like the energy challenge or managing the environment. This workshop and hands-on tutorial has taught and discussed the concepts, theories, and methods that are expected to play a central role in future materials design and novel materials discovery: • Ground state and electronically excited states based on density-functional theory also with advanced functionals, including exact exchange approaches, TD-DFT, many-body perturbation theory • Electron-vibrational coupling, heat transport, and electron transport • Ab initio electronic-structure theory as basis for scaling approaches and multi-scale modeling for thermodynamics and statistical mechanics • Validation, verification, and limits of approximations and methods The methods have been demonstrated for both inorganic and organic materials as well as hybrids thereof. We have discussed nanostructures, clusters, (bio)molecules, solids (ordered and disordered), and liquids. We have explicitly addressed difficulties and failures of recent and ongoing research work, as knowing these is crucial for the further advancement of the field. Participants have employed the FHI-aims all-electron electronic structure package (website: aimsclub.fhi-berlin.mpg.de).

Europe/Rome Abstract. A local and gauge invariant alternative version of QCD for massive fermions, will be presented. It is underlined that its action includes vertices which eventually could had been overlooked before for the consideration of gauge theories, since at first sight, they seem as breaking power counting renormalizability. However, the fact that those terms also modify the quark propagators, to become more convergent at large momenta, strongly suggests that theory is in fact renormalizable. Accepting this view, it also can be argued that all the four fermions terms constituting the Nambu-Jona-Lasinio models, could be included as counterterms in a slightly generalized renormalization procedure for massless QCD. The possible applications of these properties in massless SUSY models will be underlined. ICTP ICTP pio@ictp.it

Europe/Rome Abstract We discuss a model Kondo-type Hamiltonian representing an analytically tractable version of the model used by Yin et.al., Phys. Rev. B 86, 2399 (2012) to explain the non-Fermi liquid behavior of iron chalcogenides and ruthenates in an intermediate energy range. We consider a regime where a complete screening of the local degrees of freedom proceeds in two stages described by two characteristic energy scales T_K^orb >> E_0. The first scale marks a screening of the orbital degrees of freedom and the second one marks a crossover to the regime with coherent propagation of quasiparticles. We present analytical results for the specific heat and magnetic susceptibility at T << T_K^orb. ICTP ICTP pio@ictp.it

Europe/Rome Abstract Elastic backscattering of electrons moving along the helical edge is prohibited by time-reversal symmetry (TRS). We demonstrate, however, that an ensemble of magnetic impurities may cause TRS-preserving quasi-elastic backscattering, resulting in interference effects in the conductance. The characteristic energy transferred in a backscattering event is suppressed due to the RKKY interaction of localized spins (the suppression is exponential in the total number of magnetic impurities). We predict the statistics of conductance fluctuations to differ from those in the conventional case of a one-dimensional system with quenched disorder. Reference: V.Cheianov, L.Glazman, Phys. Rev.

Europe/Rome Abstract: In this talk I focus on the low temperature expansion of the first law of thermodynamics for near-extremal black holes and derive "laws of extremal black hole dynamics" and show that for extremal black holes with non-vanishing entropy, the leading order contribution yields an expression for their extremal entropy in agreement with the entropy function result and the Cardy formula for the entropy of a two dimensional chiral conformal field theory (CFT). When their entropy vanishes due to the vanishing of a one-cycle on the horizon, such leading contribution is always compatible with the first law satisfied by a BTZ black hole. These results are universal and consistent both with the presence of local AdS2 and AdS3 near horizon throats for extremal black holes and with the suggested quantum microscopic descriptions (AdS2/CFT1, Kerr/CFT and EVH/CFT).

Europe/Rome Abstract: Titanium dioxide (TiO2¬) is a widely used material with many industrial applications. Because of the photocatalytic activity and environmental compatibility, it has tremendous potential applications in solar cells, dye industries, electronic devices, sensors and transformers. Density functional - pseudopotential calculations were performed to study the effect of hydrogen doping in bulk, and also H-doping and oxygen vacancy on electronic structure and stability of (001) surface of TiO2 in the anatase phase. In the framework of ab-initio atomistic thermodynamic, we argue that the anatase TiO2 prefers a defected oxygen layer termination in the (001) direction. The obtained electronic structures indicate that deep hydrogen doping in this stable termination creates a mid-gap state about 0.52 eV below the conduction band and hence decreases the band gap of the system. This phenomenon may explain the enhanced photocatalytic activity of the anatase TiO2 (001) surface after hydrogenation. ICTP ICTP pio@ictp.it

Seminar Start Time: 12:00

Europe/Rome Abstract: The effect of hole doping on the Tight-Binding (TB) model of the Cu-O planes in the La2CuO4 constructed in previous works is investigated here. Firstly, it is pointed out that the model employed constitutes a generalization of the Hubbard one for the same system. Thus, the former predictions of the insulator gap, antiferromagnetic (AF) character and the existence of a paramagnetic-pseudogap (PPG) state at half-filling, become natural ones to be expected from this more general picture. The effect of hole doping on the antiferromagnetic-insulator state (AFI) and the paramagnetic-pseudogap one at half-filling, is investigated here at T = 0 K. The results predict the occurrence of a quantum phase transition (QPT) from the antiferromagnetic- insulator state at low doping to a paramagnetic-metallic state (PM) at higher hole densities. Therefore, a clear description of the hidden QPT laying beneath the “dome” in high critical temperature (HTc) superconducting materials is found. At low doping, the systems prefers the AFI state, and at the critical value of the doping density dc = 0.2, the energy of a metallic state starts becoming lower. The evolution with small doping values of the band spectrum of the AFI state, shows that the holes tend to become localized at the middle of the sides of the reduced Brillouin zone (BZ). Then, when passes through the critical value, the holes of the AFI state move to become situated at the corners of the same reduced BZ, showing in this way a structural change at the phase transition point. It suggests that the Kramers degeneration in combination with the spin-spatial entangled nature of the hole states, can lead to a new kind of pair interaction between two holes. The binding energy value is estimated as a function of the screening. ICTP ICTP pio@ictp.it

Europe/Rome Abstract. The isotropy and homogeneity of the cosmic microwave background (CMB) favors "scalar driven" early Universe inflationary models. Non-scalar fields, and in particular gauge fields, are on the other hand commonplace in all high energy particle physics models proposed to be at work at the upper bound on energy scale of inflation set by the current CMB observations. In this review we consider the role and consequences, theoretical and observational, that gauge fields can have during inflationary era. Gauge fields may be turned on in the background during inflation, or may become relevant at the level of cosmic perturbations. There have been two main class of models with gauge fields in the background, models which show violation of cosmic no-hair theorem and those which lead to isotropic FLRW cosmology, respecting the cosmic no-hair theorem. Models in which gauge fields are only turned on at the cosmic perturbation level, may source primordial magnetic fields. We also review specific observational features of these models on the CMB and/or the primordial cosmic magnetic fields. Our discussions will be mainly focused on the inflation period, with only a brief discussion on the post inflationary (p)reheating era. ICTP ICTP pio@ictp.it

Europe/Rome Abstract. I will explain the spectator scenario and show its advantages compared to the curvaton scenario, under the latest Planck constraints. The spectator scenario generates a smaller non-Gaussianity, negligible isocurvature perturbations, and less tuning. It agrees well with the current Planck data in the visible sector inflation setup, as an example. It also explains the CMB dipole asymmetry with a brief fast roll phase. I will close the talk by proposing the CMB power multipoles, as an alternative approach independent of the CMB dipole asymmetry model. ICTP ICTP pio@ictp.it

Europe/Rome We consider a quantum quench of the trap frequency in a system of bosons interacting through an inverse-square potential and confined in a harmonic trap (the harmonic Calogero model). We determine exactly the initial state in terms of the post-quench eigenstates and derive the time evolution of simple physical observables. Since this model possesses an infinite set of integrals of motion (IoM) that allow its exact solution, a generalised Gibbs ensemble (GGE), i.e. a statistical ensemble that takes into account the conservation of all IoM, can be proposed in order to describe the values of local physical observables long after the quench. Even though, due to the presence of the trap, physical observables do not exhibit equilibration but periodic evolution, such a GGE may still describe correctly their time averaged values. We check this analytically for the local boson density and find that the GGE conjecture is indeed valid, in the thermodynamic limit. SISSA, Santorio Building, Room 5 (Ground floor) ICTP pio@ictp.it

Studying “versatile lattice versions of these systems” open new doors to quantum simulation, similar to ultra-cold atoms in optical lattices. In this Talk, we review our recent theoretical progress regarding (i) the development of methods to address the dynamics of driven and dissipative light-matter systems beyond the weak-coupling limit and (ii) the realization of topological phases of light in superconducting QED-circuit arrays through synthetic gauge fields. Effects of disorder will be studied. We also comment on the current experimental status in circuit QED systems. ICTP ICTP pio@ictp.it

Europe/Rome Due to experiments in cold-atomic gases, the study of quantum quenches has become an active topic of research. While many rigorous results exist for exactly solvable "free" theories, not much is known about the effect of non-linearities, especially at long times and for systems in the thermodynamic limit, where numerical studies are challenging. In this talk, in order to highlight the main questions, I will first present results for a quench in an exactly solvable theory, namely the Luttinger model. I will then present results for the effect of various non-linearities such as a commensurate periodic potential and a local back-scattering potential. I will show that the dynamics following a quench can be quite complex by being characterized by three regimes. One is a short time perturbatively accessible regime which depends on microscopic parameters, the second is an intermediate time prethermalized regime where inelastic effects are weak and correlation functions show universal scaling behavior which is quantified by a nonequilibrium generalization of the Callan-Symanzik equations. The third is a long time regime where inelastic effects become important. For the case of the commensurate periodic potential, I will show that these inelastic effects cause the system to eventually thermalize, where the thermalization time depends in a non-monotonic way on the quench amplitude.

We find that these defects are given by line bundles on the correspondence space with curvature which can be considered as a non-abelian generalization of the curvature of the Poincar\`{e} bundle. We show that the defect equations of motion encode the non-abelian T-duality transformation. The Fourier-Mukai transform of the Ramond-Ramond fields generated by the gauge invariant flux of these defects is studied. We show that it provides elegant and compact way of computation of the transformation of the Ramond-Ramond fields under the non-abelian T-duality. ICTP ICTP pio@ictp.it

Europe/Rome Abstract. The discovery of the accelerating expansion of the Universe is motivating an impressive amount of theoretical and observational activity. After briefly reviewing the problems and challenges of "Dark Energy", I will focus on recent and ongoing works where a unifying description of dark energy and modified gravity is proposed, that is inspired by the Effective Field Theory (EFT) of Inflation formalism. By extending such a framework to late time cosmology one can write the most general action for cosmological perturbations in the presence of an additional scalar degree of freedom. I will focus on a few operators that are quadratic in the perturbations and which appear in non-minimally coupled scalar-tensor gravity and "Galileon" theories and describe the mixing between gravity and the scalar degree of freedom that such operators produce. I will also discuss the present observational constraints and forecasts for future experiments such as EUCLID. ICTP ICTP pio@ictp.it
