Non-equilibrium dynamics of an interacting Fermi gas — •Johannes Kombe, Jean-Sébastien Bernier, and Corinna Kollath — HISKP, Universität Bonn

Thanks to recent experimental advances, investigating the non-equilibrium dynamics of interacting systems is now possible. Using time-dependent perturbations, one can probe from a different angle the mechanisms responsible for the collective phenomena present in correlated systems. Taking advantage of the recent progress, we investigate theoretically the evolution of a trapped three-dimensional Fermi gas during a slow interaction change. Our study, carried out on the BCS side, reveals various collective excitations.
