Random systems

Our main research focus is the statistical physics of disordered systems and the study of the collective behavior of complex assemblies of elementary components. This includes glassy systems such as spin glasses, random polymers or a jammed ensemble of colloids, quantum problems but also simpler models in a out-of-equilibrium situation, for instance ferromagnets quenched at their critical points.

This problematic naturally arises in other fields than physics, such as combinatorial optimization and inference in computer science and has become over the last few years a rapidly evolving field at the interface of many disciplines. Research exploits the cross-fertilization of ideas, methods and problems that arises within this approach.
