量子域中的光机多稳态

Optomechanical multistability in the quantum regime

C. Schulz, A. Alvermann, L. Bakemeier, H. Fehske

摘要:

经典的光机系统具有自持振荡的特征,其中不同振幅的多个周期轨道共存。我们研究如何实现这种多稳定性的量子制度,新的动力学模式出现,因为量子轨道可以在不同的经典轨道之间移动。我们从相空间的角度解释了由此产生的量子动力学,并提供了一个定量的描述自相关函数。通过这种方式,我们可以在实验上可获得的数量中识别从经典力学到量子力学的交叉的清晰动力学特征。最后,我们讨论了一个可能的解释,我们的结果在这个意义上,量子力学保护光学机械系统对实现在经典极限的混沌动力学。

英文摘要:

Classical optomechanical systems feature self-sustained oscillations, where multiple periodic orbits at different amplitudes coexist. We study how this multistability is realized in the quantum regime, where new dynamical patterns appear because quantum trajectories can move between different classical orbits. We explain the resulting quantum dynamics from the phase space point of view, and provide a quantitative description in terms of autocorrelation functions. In this way we can identify clear dynamical signatures of the crossover from classical to quantum mechanics in experimentally accessible quantities. Finally, we discuss a possible interpretation of our results in the sense that quantum mechanics protects optomechanical systems against the chaotic dynamics realized in the classical limit.
