Localization and control in driven quantum matter

ORAL  · Invited

Abstract

Degenerate gases are a flexible testbed for the control and study of quantum matter driven far from equilibrium. I will highlight recent experimental progress in this area, from the observation of light-induced critical phases to exotic stabilization dynamics under ultra-strong driving to the realization of interactive quantum matter, in which unitary dynamics are coupled with weak measurement and feedback.
