With about 30 members, an intense programme of workshops, a constant flow of visitors, and close collaborations with local scientific institutions such as SISSA, Elettra, and the University of Trieste, the Condensed Matter and Statistical Physics (CMSP) section is a vibrant international research environment for scientists from every corner of the world.

Research in the CMSP section spans some of the most exciting areas of theoretical condensed matter physics, including the physics of nanostructures, of many-body quantum systems at, or far from equilibrium, the computer simulations of fluids and solids with atomistic, molecular and electronic structure methods, and the design of new materials for renewable energy applications.

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

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

Joint ICTP/SISSA Statistical Physics Seminar: Quantum Integrated Information Theory
Integrated Information Theory (IIT) has emerged as one of the leading research lines in computational neuroscience to provide a mechanistic and mathematically well-defined description of the neural correlates of consciousness. Integrated Information quantifies how much the integrated cause/effect structure of the global neural network fails to be accounted for by any partitioned version of it. The holistic IIT approach is in principle applicable to any information-processing dynamical network regardless of its interpretation in the context of consciousness. In this talk I will describe the first steps towards a possible formulation of a general and consistent version of IIT for interacting networks of quantum systems irrespective of potential applications to consciousness. A variety of different phases, from the dis-integrated to the holistic one can be identified and their cross-overs studied.

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

Conference on Physics of Defects in Solids: Quantum Mechanics Meets Topology | (smr 3221)
Goals and brief description of the conference
Defects in crystalline solids are ubiquitous. It is the second law of thermodynamics that gives rise to the appearance of a certain amount of disorder in crystalline materials at finite temperatures. Moreover, defects can be present in synthetic materials well above the equilibrium concentration due to the imperfections of material production processes or due to the exposure of the system to irradiation with energetic particles. Such lattice imperfections have a strong influence on the electronic, optical, thermal, and mechanical properties of the solids, normally deteriorating their characteristics.
However, defects not always have detrimental effects on material properties, with the most prominent example being the doping of semiconductors by controllable introduction of impurities using ion implantation. In general, treatments of solids with beams of energetic ions and electrons have been shown to be a very powerful tool for the post-synthesis tailoring of material characteristics.
The goal of the conference is to bring together active researchers in the field, as well as several experts in the related areas, to discuss "state of the art" in theory and experiment dealing with the physics of defects in solids. The effects of impurities and point/line defects on various properties of solids will be addressed, and the attendees will be able to learn not only the experimental facts, but also understand how the defects are treated within the framework of computational and analytical methods in theoretical physics. Particular attention is going to be paid to defects in nanomaterials, as the reduced dimensionality strongly affects their behavior.
The Program will include about 20 oral presentations given by invited speakers, a poster session, and a limited number of short talks selected from contributed abstracts.
Topics to be addressed
Modern techniques (Raman spectroscopy, STM, XPS, TEM, etc.) used to assess concentration of defect in solids and identify their types
First-principles modeling of native defects and impurities
Ion and electron irradiation-induced defects
Simulations of ion impacts onto solids
Defects in superconductors
Defects in low-dimensional materials (graphene, inorganic 2D materials, nanotubes etc.)
Topological defects
Defects for quantum computing
Tutorial
The conference will be preceded by a half-day tutorial where an introduction to the techniques used to characterize the defects will be given, along with the modern computational techniques used to get theoretical insights into defect behavior.
