Study on the phase of quantum field has become one of the focal points in quantum optics. Since the Pegg-Barnett phase operator was established, the phase properties of different quantum fields and the effect of interaction between atoms and quantum fields on the phase dynamics have been widely investigated. In this paper, the phase dynamical and statistical properties of the field in the intensity-dependent coupling J-C model were studied using the Pegg-Barnett phase theory. Under certain conditions, the phase locking and squeezing are behaved, and the numb...
