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.

ICTP Seminar Series in Condensed Matter and Statistical Physics: Topological Quantum Matter Far from Equilibrium
Topological states of quantum matter such as topological insulators and superconductors have been an active field of research in physics for many years. The recent experimental progress on their realization with ultracold atomic gases raises natural questions about the notion of topological quantum matter far from thermal equilibrium. In this talk, we present our theoretical findings in this context.
We first discuss the non-equilibrium Hall response of a system initialized in a topologically trivial state before its Hamiltonian is ramped into a Chern insulator phase, comparing the coherent dynamics with effects of dephasing. In the second part of the talk, we discuss non-equilibrium properties of driven systems. In particular, we show how a perfect spin momentum locking, so far only known from edge states of two-dimensional topological insulators can emerge in the stroboscopic dynamics of one-dimensional Floquet lattice systems. Finally, we discuss dynamically defined topological quantum numbers that have no non-equilibrium counterpart, and report on their very recent experimental observation.

Joint ICTP/SISSA Statistical Physics Seminar: Non-Linear Responses, Soft Modes and the True Nature of Glasses
In understanding the nature and the formation of glasses lie questions that go beyond the physics of such amorphous materials and are relevant for many branches of science from physics to mathematics, computer science, and biology. After a general introduction to the field of glassy systems, I will show that strong non-linear responses to small perturbations and the proliferation of soft-modes are key signatures of glassiness. I will explain how we used these features to probe the nature of the glass transition and to reveal that amorphous solids may undergo a new kind of phase transition at which standard elasticity breaks down.

Condensed Matter Seminar: Anharmonic Effects on Material Properties at High Temperatures from Ab Initio Molecular Dynamics Simulations
Ab initio molecular dynamics simulation technique is a promising tool to study various properties of vibrational spectra, entropy, free energy, etc. even at high temperatures. With the harmonic phonon model, all interatomic forces are treated as purely harmonic so that the equilibrium distance between atoms is independent of temperature. At the low temperature regime, this model, commonly used in most quantum chemistry codes, can approximately model vibrational properties and free energetics. At higher temperatures, however, the harmonic model can break down since it cannot explain thermal expansion, where the role of anharmonicity becomes very important in the description and interpretation of the system. To better describe properties of systems at high temperatures, the quasi-harmonic approximation can be. In this talk, I will present a few examples to show how the quasi-harmonic approximation is used to rigorously evaluate the vibrational density of states at elevated temperatures. From this, the quantitative evaluation of thermodynamic properties such as entropy, enthalpy, free energy, and equilibrium constants can then be inferred. A variety of systems ranging from ethanol-adsorption in zeolites (catalysis),[1] water/scCO2/mineral interfaces (carbon sequestration),[2] and Tc-incorporation in magnetite (nuclear remediation)[3] are used to illustrate the power of this approach.

ICTP Seminar Series in Condensed Matter and Statistical Physics: Mechanical Signatures of the Current Blockade Instability in Suspended Carbon Nanotubes
Transport measurements allow sensitive detection of nanomechanical motion of suspended carbon nanotubes. It has been predicted that when the electromechanical coupling is sufficiently large a bistability with a current blockade appears. Unambiguous observation of this transition by current measurements may be difficult. Instead, we investigate the mechanical response of the system, namely, the displacement spectral function, the linear response to a driving, and the ring-down behavior. We find that by increasing the electromechanical coupling the peak in the spectral function broadens and shifts at low frequencies while the oscillator dephasing time shortens. These effects are maximum at the transition where nonlinearities dominate the dynamics. These strong signatures open the way to detect the blockade transition in devices currently studied by several groups.

Spring College on the Physics of Complex Systems | (smr 3113)
ICTP and SISSA, in collaboration with the partner institutions of the Master in the Physics of Complex Systems (http://www.polito.it/pcs) will organize the Spring College on the Physics of Complex Systems from 10 April to 5 May 2017.
Many complex systems in physics, biology, engineering and economics are characterized by a large number of interacting degrees of freedom giving rise to a non-trivial collective behavior. The theoretical and computational tools for a quantitative analysis of complex systems are often rooted in modern (statistical, quantum) physics. The Spring College on the Physics of Complex Systems aims to give students the opportunity to get in touch with a selection of topics at the forefront of research during an intensive 4-week program. It consists of 5 courses of 9 lectures each, followed by final written tests.
Invited Lecturers:
Pasquale Calabrese (SISSA, Trieste)
Thierry Mora (ENS, Paris)
Federico Ricci Tersenghi (U. of Rome La Sapienza)
Matthew Scott (U. of Waterloo, Canada)
Pierpaolo Vivo (King's College, London)

Workshop on Spectroscopy and Dynamics of Photoinduced Electronic Excitations | (smr 3116)
A preliminary version of our Workshop programme is online - please select relevant link (see list on the left side).
- - -
DEADLINE FOR REQUESTING PARTICIPATION EXPIRED ON 31 MARCH 2017.
- - -
In the last years there has been a tremendous progress in the investigation of dynamics of photoinduced electronic excitation in real materials, mainly thanks to developments in experimental techniques, like ultrafast spectroscopy, and in theoretical methods, like many-body perturbation theory and time-dependent density functional theory.
Processes of interest include photoabsorption, exciton dynamics, and charge transfer.
These issues are of interest for fundamental research, but are also relevant for applications in photovoltaics, optoelectronics, and photocatalysis.
Leading experts on both theoretical and experimental research of dynamics of photoinduced electronic excitations will discuss developments and future directions in understanding such dynamics, and its dependence on the materials properties.
