摘要
推导了双光子Jaynes-Cummings模型中光子统计分布函数的一般表示式,该式适用于任何初始光场和任何初始原子状态,详细研究了严格双光子共振情况下,初始为相干态和压缩态的光场在该模型中光子分布曲线的演化特征。两者呈现很大的差异。
The general expression of the statistical distribution function of photons in two-photon Jaynes-Cummings model (JCM) is derived. The expression can be applied to the cases of any initial light field and any initial atomic state. Under exact two-photon resonance, the features of evolution for the statistical distribution of photons in JCM with the initial coherent state field and the initial squeeze state field are studied in detail. These two cases show striking difference.
