论文摘要
我们演示了确定性非线性动力学的量子特征，以向广义开放式DICKE模型的超沉载过渡，具有不同的耦合强度，用于共同和反旋转的光 - 互动项。观察到向正常和超级负反位共存的一阶相变，与量子波动驱动的这两个阶段之间的开关动力学的出现相对应。我们表明，这种相共存引起了量子机械系统的磁滞回路。此外，在量子模拟中可以清楚地观察到向超值振荡阶段的过渡。
We demonstrate quantum signatures of deterministic nonlinear dynamics in the transition to superradiance of a generalized open Dicke model with different coupling strengths for the co- and counter-rotating light-matter interaction terms. A first-order phase transition to coexisting normal and superradiant phases is observed, corresponding with the emergence of switching dynamics between these two phases, driven by quantum fluctuations. We show that this phase coexistence gives rise to a hysteresis loop also for the quantum mechanical system. Additionally, a transition to a superradiant oscillatory phase can be observed clearly in quantum simulations.
