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.

腔-BEC系统中订单的动态控制

我们演示了通过周期性驱动泵浦激光器对腔BEC系统的超辐射过渡进行动态控制。我们表明，超辐射态的主密度波阶可以被抑制，并且玻色-爱因斯坦凝聚的次要竞争阶在稳定状态下出现。此外，我们表明可以动态地稳定不存在于平衡中的其他非平衡密度波阶。最后，对于强力驱动，出现了混沌动力学。
