| 摘 要： | 利用细致平衡原理和熵的演化，研究了与压缩真空态光场进行简并双光子耦合的两能级系统的稳定性．发现当压缩真空态光场的压缩参数较小时，系统是不稳定的；而当压缩真空态光场的压缩参数为实数并且很大时，系统达到一种远离平衡态的稳定状态．关键词：

| Abstract: | Using the principle of detailed balance and the evolution of entropy, the stability of a two-level system coupled to a squeezed vacuum via degenerate two-photon processes is investigated. We find that the stability of the system depends on the squeezing parameter M of squeezed vacuum. When |M| is small, the system is unstable, but when M is a very large real number, the system is driven to a stable state but far from equilibrium. |
