Dynamical Control of Order in a Cavity-BEC System

Understand

We demonstrate dynamical control of the superradiant transition of cavity-BEC system via periodic driving of the pump laser.

• We show that the dominant density wave order of the superradiant state can be suppressed, and that the subdominant competing order of Bose-Einstein condensation emerges in the steady state.
• Furthermore, we show that additional, non-equilibrium density wave orders, which do not exist in equilibrium, can be stabilized dynamically.
• Finally, for strong driving, chaotic dynamics emerges.
