Dynamic thermalisation hypothesis postulates that a typical isolated many-body system starting from a nonequilibrium state is overwhelmingly likely to reach thermal equilibrium under the action of its internal dynamics.

Ilya Gruzberg (Université d’État de l’Ohio, États-Unis) Summary : Anderson transitions (ATs) between metals and insulators or between topologically distinct insulators, share common features with conventional second-order phase transitions, such as the critical point of the Ising model for a magnet. However, ATs also exhibit many unusual features including the multifractal scaling of the critical… Read More »Anderson transitions and (lost) conformal invariance – (Ilya Gruzberg / Seminar / LPT). – 11/10/2022

Mateo Uldemolins-Nivela (LPS, Orsay)   Summary A magnetic impurity on a conventional superconductor is one of the most simple pair-breaking defects that induces in-gap Yu-Shiba-Rusinov (YSR) bound states, whose intricate spatial structure crucially influences the possibilities of engineering collective impurity states (e.g., Shiba chains, lattices...) and topological superconductivity. In this talk, I will first introduce… Read More »Yu-Shiba-Rusinov states in two-dimensional superconductors. – (Mateo Uldemolins-Nivela / Seminar / LPT). – 08/11/2022
