Aging of spin glasses: the case of the random energy model

Vortrag von Dr. Jean-Christophe Mourrat

Sprecher eingeladen von: Prof. Dr. Jean Bertoin

Physically, glassy systems are characterized by the phenomenon of aging: over every time-scale accessible to the experiment, the properties of the system evolve without reaching equilibrium. In this talk, we will focus on possibly the most basic mean-field model of a spin glass, called the random energy model. I will begin by describing heuristics that enable to predict the aging properties of dynamics on this model. I will then present recent rigorous results confirming these heuristics, which hold for a large class of natural dynamics. (Joint work with Pierre Mathieu.)
