#### Abstract

The considered system is two independent two-level atoms interacting with a two-mode electromagnetic field (EMF), taking into account the coupling function between atoms and field to be time-dependent. The systems corresponding state function is obtained when the two atoms are initially made in superposition of states and the coherent state of the field is taken. By increasing the value of kerr-like medium parameter $\chi$ and time varying parameter $\varepsilon$ enhances the number of artificial phase jumps and the chaotic behavior period. We discuss the effect of time-variation coupling and kerr-like medium on atomic inversion, Pancharatnam phase, Husimi Q function and correlation function.
