On the interaction between two two-level atoms and a two mode cavity field in the presence of detuning and cross-Kerr nonlinearity

In this paper, the interaction between two two-level identical atoms and two modes has been discussed. The detuning parameters and the cross-Kerr nonlinearity have been taken into account. The exact solution of this model when the atoms are initially prepared in their excited or ground states has been obtained. The time-dependent parameters of the anti-bunching of photons, the coherent properties, the normal squeezing and the sum squeezing have been calculated. The effects of the detuning and cross-Kerr nonlinearity on the temporal behavior of these parameters have been analyzed. The results showed that the considered atomic system is sensitive to variations in both the detuning and the cross-Kerr nonlinearity parameters.
