Abstract
In this paper, we introduce a modified class of correlated coherent states. These states are realized during the consideration of a new model which represents the interaction between a two- level atom and two electromagnetic fields injected simultaneously within a cavity. By using the transition amplitude we have managed to establish the relationship between the usual coherent states and the modified states. The phenomenon of squeezing and the variances of the photon number sum and difference are discussed. It has been shown that the mean photon number controls the value of the correlation. Furthermore, our discussion on the quasi-probability distribution functions (the Wigner and Q-functions) shows that both functions are sensitive to the change in the ratio of the field modes as well as the coupling parameter lambda(1).
