论文摘要
我们表明，光机电量子系统可以在小非线性相互作用和强大的外部驱动器的极限内进行耗散相变。在这种定义的热力学极限中，非线性相互作用稳定了强和超肌耦合方案中的光力动力学。结果，光力学系统具有丰富的相图，其中包括周期性轨道，不连续的和连续的耗散相变，有和不进行分叉。我们还发现了一个临界点，连续和不连续的相变符合线。我们的分析表明，光学系统对于理解耗散相变和超级耦合方案的丰富物理学是有价值的。
We show that optomechanical quantum systems can undergo dissipative phase transitions within the limit of small nonlinear interaction and strong external drive. In such a defined thermodynamical limit, the nonlinear interaction stabilizes optomechanical dynamics in strong and ultrastrong coupling regimes. As a consequence optomechanical systems possess a rich phase diagram consisting of periodic orbits, discontinuous, and continuous dissipative phase transitions with and without bifurcation. We also find a critical point where continuous and discontinuous dissipative phase transition lines meet. Our analysis demonstrates that optomechanical systems are valuable for understanding the rich physics of dissipative phase transitions and ultrastrong coupling regimes.
