EXACT SOLUTION OF THE DYNAMIC PROPERTIES OF AN ATOM INTERACTING WITH THE MULTICHROMATIC RADIATIVE FIELD
原子与多模辐射场作用的动力学性质的精确求解

The dynamics of a two-level atom interacting with a multichromatic radiative field is solved exactly without the r0tating - wave approximation and dipole approximation. By the technique of coherent state expansion,we can investigate the variance of the population in up and down levels of the atom with time in the procedure of interaction and the number of the photon of the system. Some meaningful results are presented by the simulation of the computer.
