摘　　要：提出了一个由三能级级联原子去纠缠光学振荡器和腔场的方案。研究结果表明,在原子介质存在的情况下,可以得到更大值的光机械系统的稳态宏观纠缠。此外,动镜与腔场纠缠对腔场衰减不敏感,可以弥补腔耗散的影响。A scheme for three-level cascade atoms to entangle an optomechanical oscillator and a cavity field is presented.In the presence of atomic mediums,the result shows that the larger stationary macroscopic entanglement of optomechanical system can be obtained and quantified by logarithmic negativity.Moreover,we find that it is insensitive to the cavity decay rate for the entanglement between movable mirror and cavity field,which makes up for the effects of the cavity losses.
