We study the interaction between a moving four-level atom and one-mode field in the presence of Kerr like medium and obtain the exact solution of the model. The atomic inversion, Field entropy, Purity and Fidelity have been examined under various values of detuning, the Kerr-like medium and the time-dependent coupling. We show that, the present system is a good candidate for building the quantum devices, where the mentioned parameters can be used controllers. Finally, playing with the initial states setting, one can obtain new features of the entanglement.
