摘要
本文考虑了一个三能级原子与双模动腔系统相互作用的理论方案.通过量子朗之万方程给出了系统的稳态解,并得出入射率(耦合系数)增大,光子数变少;利用输入输出理论,数值模拟了两模腔场之间的纠缠压缩谱.研究表明原子的入射率及镜子的振动频率影响双模场的输出压缩谱.
The theory scheme is proposed for the three - level atoms coupled to two - mode cavities. Employing the quantum Langevin equation, the steady state of the hybrid system was obtained. The results show that with the increasing of the injection rate （ coupling）, the photon number in the cavities decreased. Applying the input - output relation for the two - mode fields, We indicate the two - mode output squeezing spectrum via a nu- merical method. The results show that the injected rate of atom and the frequency of the mirror oscillation affect the oumut entanzlement of the two - mode fields.
