We simulate an optomechanical system via a cavity QED scenario with a movable atom and investigate its application in the tiny mass sensing. We find that the steady-state solution of the system exhibits a multiple stability behavior, which is similar to that in the optomechanical system. We explain this phenomenon by the opto-mechanical interaction term in the effective Hamiltonian. Due to the dressed states formed by the effective coupling between the vibration degree of the atom and the optical mode in the cavity, we observe a narrow transparent window in the output field. We utilize this vibration induced transparency phenomenon to perform the tiny mass sensing. We hope our study will broaden the application of the cavity QED system to quantum technologies.
我们通过具有可移动原子的腔量子电动力学方案模拟了一个光机械系统,并研究了其在微小质量传感中的应用。我们发现该系统的稳态解呈现出多重稳定性行为,这与光机械系统中的情况类似。我们通过有效哈密顿量中的光机械相互作用项来解释这一现象。由于原子的振动自由度与腔内光学模式之间的有效耦合形成了缀饰态,我们在输出场中观察到一个狭窄的透明窗口。我们利用这种振动诱导透明现象来进行微小质量传感。我们希望我们的研究将拓宽腔量子电动力学系统在量子技术中的应用。
