• Abstract: Floquet engineering, in which the properties of a quantum system are modified through the application of strong periodic drives, is an indispensable tool in atomic and condensed matter systems. However, it is inevitably limited by intrinsic heating processes. We describe a simple autonomous scheme, which exploits a static coupling between the driven system and a lossy auxiliary, to cool large classes of Floquet systems into desired states. We present experimental and theoretical evidence for the stabilization of a chosen quasienergy state in a strongly modulated transmon qubit coupled to an auxiliary microwave cavity with fixed frequency and photon loss. The scheme naturally extends to Floquet systems with multiple degrees of freedom. As an example, we demonstrate the stabilization of topological photon pumping in a driven cavity-QED system numerically. The coupling to the auxiliary cavity increases the average photon current and the fidelity of non-classical states, such as high photon number Fock states, that can be prepared in the system cavity.

  We study subradiance in a Bose-Einstein condensate positioned at the mode crossing of two optical cavities. metastable density structures that suppress emission into one cavity mode prevent relaxation to the stationary, superradiant grating. We reproduce these dynamics by a quantum mean field model, suggesting that subradiance shares characteristics with quasi-stationary states predicted in other long-range interacting systems.
