Universality far from equilibrium: From the early universe to ultracold quantum gases

Jürgen Berges

In recent years there have been important advances in understanding isolated quantum systems far from equilibrium. Prominent examples include the (pre-)heating process in the early universe after inflation, the initial stages in collisions of relativistic nuclei at giant laboratory facilities, as well as table-top experiments with ultracold quantum gases. Even though the typical energy scales of these systems vastly differ, they can show very similar dynamical properties. Certain characteristic numbers can even be quantitatively the same, defining nonthermal universality classes. One may use this universality to learn from experiments with cold atoms aspects about the dynamics during the early stages of our universe.
