Statistical Physics out of equilibrium
Leticia Cugliandolo (LPTHE, Sorbonne Université, Paris)
Equilibrium statistical physics provides a bridge between microscopic
dynamics and macroscopic behavior. It explains the emergence of
thermodynamic concepts such as temperature and pressure, and accounts for
collective phenomena like phase transitions. By contrast, a comparable
understanding of systems out of equilibrium remains elusive, and is the
focus of intense research across many areas of physics. In this talk, I
will concentrate on a particular class of nonequilibrium dynamics: those
realized in classical integrable systems. I will demonstrate how modest
extensions of standard statistical physics tools can capture the long-term
behavior of these systems in various ways, illustrating the results with a
simple model.
