论文摘要
研究了包含振动镜的激光泵型光学样品中的多音量量子动力学。尤其是,我们专注于分散交互制度,从光谐振器频率引起的外部应用相干场频率不等于镜像的振荡频率或其倍数。结果,对于所涉及子系统之间的适度强耦合,该复杂系统的量子动力学分别通过多条带吸收或发射过程来描述。特别是,我们展示了通过光子检测来监视声子量子动力学的有效方法。还讨论了提取相关样品参数的可能性,例如,还讨论了机械镜和电磁场之间的耦合强度。
The multiphonon quantum dynamics in laser-pumped cavity optomechanical samples containing a vibrating mirror is investigated. Especially, we focus on dispersive interaction regimes where the externally applied coherent field frequency detuning from the optical resonator frequency is not equal to the mirror's oscillating frequency or to its multiples. As a result, for moderately strong couplings among the involved subsystems, the quantum dynamics of this complex system is described by multiphonon absorption or emission processes, respectively. Particularly, we demonstrate efficient ways to monitor the phonon quantum dynamics via photon detection. The possibility to extract the relevant sample parameters, for instance, the coupling strength between the mechanical mirror and the electromagnetic field, is also discussed.
