论文摘要
对于非线性腔谐振器中两个耦合骨模式的驱动 - 脉冲系统，我们演示了从微不足道稳态到两个不同的耗散时间晶体相的一系列相变。这些效应已经在使用分叉理论的Lindblad方程的半经典分析水平上预计，并得到了完整的量子（数值）处理的进一步支持。预测该系统将表现出不同的动力阶段，其特征是具有非平凡周期性的振荡非平衡稳态，这是时间晶体的标志。我们希望可以在各种腔QED实验中直接探测这些阶段。
For the driven-dissipative system of two coupled bosonic modes in a nonlinear cavity resonator, we demonstrate a sequence of phase transitions from a trivial steady state to two distinct dissipative time crystalline phases. These effects are already anticipated at the level of the semiclassical analysis of the Lindblad equation using the theory of bifurcations and are further supported by the full quantum (numerical) treatment. The system is predicted to exhibit different dynamical phases characterized by an oscillating non-equilibrium steady state with non-trivial periodicity, which is a hallmark of time crystals. We expect that these phases can be directly probed in various cavity QED experiments.
