Title of Talk: Hydrodynamic attractor in periodically driven ultracold quantum gases

Abstract:

Hydrodynamic attractors are a universal phenomenon of strongly interacting systems that describe the hydrodynamic-like evolution far from local equilibrium. In particular, the rapid hydrodynamization of the Quark-Gluon Plasma is behind the remarkable success of hydrodynamic models of high-energy nuclear collisions. Until now, hydrodynamic attractors have been studied only in monotonically expanding systems, e.g., Bjorken expansion. In this work, we show that a system undergoing an oscillating isotropic expansion exhibits a novel attractor behavior that resembles a limit cycle in dynamical systems. This phenomenon can be studied in ultracold quantum gases with an externally modulated scattering length, which opens a new way to the experimental discovery of a hydrodynamic attractor.
