单个二能级原子和单模辐射场相互作用组成的JCM模型是量子光学中的重要研究对象。初始场为相干态光场、热光场以及相干志和热光场的混合光场等各种情况下的原子反转和光场统计已有较多的工作。近年来由于对压缩志光场的深入研究(理论的和实验的),讨论初始场是压缩态光场的JCM的工作已陆续出现,但一般讨论原子反转特性较多,对光场统计讨 The JCM model composed of the interaction of a single two-level atom and a single-mode radiation field is an important research object in quantum optics. The initial field is a coherent state light field, the thermal field and coherence and thermal field mixed light field under various circumstances, such as atomic inversion and light field statistics have been more work. In recent years, due to the deep research (theoretical and experimental) on the compressive optical field, the work of discussing the JCM with the initial field being the squeezed state optical field has appeared one after another. However, it is generally discussed that there are many atomic inversion features,
