We first calculate the transition probabilities between cavity field states; this is accomplished by exploiting the Feynman-Dyson expansion of the (interaction picture) evolution, truncated at the first order, and then tracing out the reservoir degrees of freedom. Then we obtain the equations of motion for the expectation value of the number operators of photons in the two modes of the f-deformed cavity field. Finally, we study cross correlation between the modes of a two-mode field, which is quantified by the cross correlation function.

The first section discusses the theoretical model of the interaction between a two-mode cavity-field and an effective two-level atom within the framework of an f-DJCM without the rotating wave approximation. After that, we obtain the reduced density matrix of the atom with and without the rotating-wave approximation. Then, we have investigated the effect of the counterterm on temporal evolution of various nonclassical properties of the atom, i.e., atomic population inversion, atomic dipole squeezing and atom-field entanglement. Particularly, we compare the numerical result for three different values of the deformation parameter q (q=1, q=1.1, q=1) with and without the rotating wave approximation.
