摘要: The pure state dynamical evolution of the atomic as well as the field states in the two-photon Jaynes Cumming model with a Kerr-like medium for the field initially in the coherent state is investigated under the high-field approximation ($\bar{n}$>>1). Analytic expressions of the disentanglement conditions and the relevant disentangled states are derived, which are closely related to Kerr nonlinear coupling constant. This study also reveals that the initial atomic excited state can be evolved into the atomic dipole squeezed state.
