Glass transition in molecular liquids: RG approach and Ising-like effective theories

There remains a wide divergence of views concerning the appropriate theoretical framework for understanding the nature of the glass transition. In the ongoing search, the Random First-Order Transition (RFOT) theory has proven to be a strong candidate, establishing what appears to be an intricate mean-field (MF) description of supercooled liquids and glasses. This MF treatment predicts a scenario with two critical temperatures T_A and T_K, the upper one T_A being a dynamical singularity and the lower one T_K a thermodynamic ideal  glass transition characterized by a vanishing of the configurational entropy (i.e., the logarithm of the number of metastable states). To make progress toward a theory of the glass transition, one must, however, go beyond the MF description and include the effect of fluctuations in finite-dimensional systems with finite-range interactions.

Static properties of 2D spin-ice as a sixteen-vertex model

Many interesting classes of classical and quantum magnetic systems are highly constrained. In particular, geometric constraints lead to frustration and the impossibility of satisfying all competing interactions simultaneously, giving rise to the existence of highly degenerate ground states. In conventional spin-ice, topological frustration arises from the fact that the Ising axes in the unit cell are fixed and different, forced to point towards the centers of neighboring tetrahedra. The configurations that minimize the energy of each tetrahedron are the six states (or vertices) with two-in and two-out pointing spins. Recently, the interest in spin-ice physics has been boosted by the advent of artificial samples on simpler square lattices.

Anderson localization and Random Matrices

Beyond a critical amount of disorder, the electrons are trapped and their diffusive motion comes to a complete halt. This phenomenon, for which P. Anderson won the Nobel prize in 1977, still reveals new facets and subtleties. On the one hand, it plays a central role in many areas of science, such as transport in disordered quantum systems (Many Body Localization), random matrices, and Quantum chaos. On the other hand, despite almost 60 years of research, the study of AL remains an active field with various unsolved problems.
In particular the  localization transition between the metallic and the insulating phase in the limit of large dimension is not yet completely understood.

Statistical physics approach to micro and macroeconomy. Agent based models for economic instabilities and crises

Inferring  the  behaviour  of  large  assemblies  from  the  behaviour  of  its  elementary constituents  is  arguably  one  of the most important problems in a host of different disciplines:
physics, material sciences, biology, computer sciences, sociology  and,  of  course,  economics. It is also a notoriously hard problem. Statistical  physics  has developed in the last 150 years essentially to understand this micro-macro link. In the framework of the European project CRISIS (http://crisis.oxalto.co.uk), we have explored the possible types of phenomena that simple macroeconomic Agent-Based models (ABM) can reproduce, proposed a methodology, inspired by statistical physics, which offers a key tool to characterize a model: its phase diagram in the space of parameters, which allows one to unveil the skeleton of the ABM.
