AB - In this framework, the effect of a Kerr-like medium and the coupling function  dependent on the number of photons operator on the interaction between a  two-level atom and a non-linear field is studied. A relation between the  Kerr-like medium parameter and the field-atom coupling parameter is used to  obtain a simplified formula for Rabi frequency. The wave function of the  proposed model is obtained, followed by the derivation of the phase  distribution and from which the wehrl entropy formula is calculated. The  effect of the initial state and the non-linear func­tion dependent on the  number of photons operator and the Kerr-like medium on entanglement is  calculated through the Wehrl entropy formula, wehrl distribution and the  behaviour of photons by studying the correlation function. The entangle­ment  decreases when the function dependent on the number of photons operator is  taken into account, while the entanglement gradually improves when the  squeezed state is considered, and the entanglement decreases significantly  when considering the Kerr medium. An oscillatory distribution is formed  between the classical and non-classical in the coherent state. The  non-classical distribution disappears when considering the squeezed state  and the Kerr-like medium.
