DYNAMICS OF 2-LEVEL ATOM WITH MOVING MASS CENTER CONSIDERING THE MULTIPHOTON TRANSITIONS

We study the effect of moving mass center on atomic dynamics for vario us initial conditions, and the two-level atom coupled locally in inhom ogeneous cavity to a near-resonant single-mode quantized field and the atomic levels are coupled by the multiphoton transitions. Our study s hows that, the Doppler effect exercised by the motion of atom can lead to the modified phenomenon of oscillation collapse and revival in the atomic population inversion at the beginning of evolution.
