We present an alternative scheme to achieve Schrödinger cat states in a strong coupling hybrid cavity optomechanical system. Under the single-photon strong-coupling regime, the interaction between the atom-cavity-oscillator system can induce the mesoscopic mechanical oscillator to Schrödinger cat states. Comparing to previous schemes, the proposed proposal consider the second order approximation on the Lamb-Dicke parameter, which is more universal in the experiment. Numerical simulations confirm the validity of our derivation.
我们提出了一种在强耦合混合腔光机械系统中实现薛定谔猫态的替代方案。在单光子强耦合 regime 下，原子 - 腔 - 振荡器系统之间的相互作用可诱导介观机械振荡器进入薛定谔猫态。与先前的方案相比，所提出的方案考虑了兰姆 - 迪克参数的二阶近似，这在实验中更具普遍性。数值模拟证实了我们推导的有效性。
