Interactions of two two-level atoms with a single-mode quantized radiation field are studied, and exact expressions for the atom-field probability amplitudes in the rotating-wave approximation are presented. These solutions are employed in the study of the quantum collapse and revivals of the atomic coherence.

The quantum mechanical analysis for a non-resonant case of a single radiation mode interacting with a two-level atom in a cavity is studied. Expressions for the mean value of photon number and the time evolution of the atomic motion are given. The frequency of exchange energy between the atomic levels and the radiation field systems for non- resonant and resonant interactions is obtained. Results for all initial states of the atom-radiation field are presented. Results for resonant and non-resonant interactions are compared.

The squeezing of the electromagnetic field for M two level atoms existing in the Dicke state |r, m〉 and interacting with a single mode coherent radiation has been investigated under an approximation based on a fully quantum mechanical approach. The time dependent variance has been calculated and the influence of the number of photons and some other parameters are noted.
