PHASE FLUCTUATIONS IN JAYNES-CUMMINGS MODEL WITH AND WITHOUT ROTATION WAVE APPROXIMATION
旋波近似和非旋波近似下Jaynes-Cummings模型中光场位相涨落

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.
