Description

The realization of homogeneous quantum gases trapped in optical boxes has been a milestone in quantum simulation [1]. These textbook systems are proving to be powerful playground to study out of equilibrium physics in clean settings. I will present some of our recent works on driven uniform Fermi systems: the strong-drive spectroscopy of Fermi polarons [2], the measurement of the Lindhard response [3], and the observation of the emergence and breakdown of Fermi’s golden rule in a driven universal Fermi gas.
