论文摘要
我们提出了一种在高度未解决的侧带(HURSB)状态下在混合原子原理系统中生成强大的机械挤压的方案,在该系统中,空腔的衰减速率比机械振荡器的频率大得多。该系统由两个两级原子集合和一个具有不同振幅不同激光器驱动的腔的光学机械系统形成。在HURSB制度中,如果没有原子合奏或仅将一个原子合体放入光学机械系统,则可移动镜的挤压不得大于3dB。但是,如果将两个原子集合放入光学机械系统中,即使在HURSB制度中,也可以实现强大的机械挤压。我们的方案铺平了实施实验中混合原子机电系统中强大的机械挤压超过3db的道路。
We propose a scheme for the generation of strong mechanical squeezing beyond 3dB in hybrid atom-optomechanical systems in the highly unresolved sideband (HURSB) regime where the decay rate of cavity is much larger than the frequency of the mechanical oscillator. The system is formed by two two-level atomic ensembles and an optomechanical system with cavity driven by two lasers with different amplitudes. In the HURSB regime, the squeezing of the movable mirror can not be larger than 3dB if no atomic ensemble or only one atomic ensemble is put into the optomechanical system. However, if two atomic ensembles are put into the optomechanical system, the strong mechanical squeezing beyond 3dB is achieved even in the HURSB regime. Our scheme paves the way toward the implementation of strong mechanical squeezing beyond 3dB in hybrid atom-optomechanical systems in experiments.
