三能级原子与双模动腔系统的稳态求解

Steady state solution of three-level atoms coupled to optomechanical system

在原子与双模动腔共同存在的量子系统中,原子、腔场以及移动的镜子之间都会发生相互作用.考虑了一个三能级原子与双模动腔所组成的光机械系统,应用量子朗之万方程,讨论了由V型三能级原子束与双模动腔组成的系统中稳态解的求解方法.由所求的结果可看出,原子介质的存在能影响光子的有效衰减率以及腔场和两个镜子之间的辐射压.

In a quantum system where atoms are coupled to an optomechanical system, the interaction between each component such as atoms, cavity field and moving mirror is inevitable. In the paper, we consider an optomeehanical system consisted of V-type three level atoms and two-mode moving cavity. We discuss the steady state solution of the system by quantum Langevin equations. The results show that the existence of the atomic medium affects the effective decay rate of the photon and the radiation pressure of the cavity field upon two mirrors.
