| 摘 要： | 本文讨论在旋波近似和非旋波近似下Jaynes-Cummings(缩写为J-C)模型中光场位相随时间的演化。解析分析证明原子的Rabi振荡将导致相干光场的位相扩散,虚光场的影响能够展现系统的量子噪声,并且使光场频率发生漂移。关键词：

| Abstract: | In this paper, we have respectively investigated the time evolution of the phase operator of radiation field in the Jaynes-Cummings model with and without RWA. We verified that the atomic Rabi oscillation leads to the phase dissipation of radiation field by analytical method, and the effect of virtual field can exhibit the quantum fluctuations of system and leads to the frequency shift of radiation field. |
