Dynamics of Two-Level Atom with Moving Mass Center Considering the Multiphoton Transitions
Yi Xue-Xi
Abstract
We study the effect of moving mass center on atomic dynamics for various initial conditions, and the two-level atom coupled locally in inhomogeneous cavity to a near-resonant single-mode quantized field and the atomic levels are coupled by the multiphoton transitions. Our study shows 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.
