Influence of the Kerr-Like Medium and the Detuning Parameter on Statistical Aspects of Intensity Dependent Coupling Hamiltonian.
Magdy E. Amin, N.H. Abdel-Wahab, and M. Taha

We study the interaction between a one-mode electromagnetic field and a two-level atom in the presence of a Kerr-like medium when atom is prepared initially in the momentum eigenstate. The wave function is calculated by using the Schrodinger equation for a coherent electromagnetic field and an atom in the excited state. The effects of the Kerr-like medium and the detuning parameters on statistical aspects of the intensity dependent coupling Hamiltonian such as, atomic momentum increment, momentum diffusion, the radiation force and the field entropy are calculated. We investigate the effect of the detuning, Kerr-like medium and photon number operator on the field entropy. It is found that the field entropy is affected by these parameters.
Key words: Schrodinger equation, two-level atom, electromagnetic interaction
