摘要
利用Milburn理论，给出了初始时二能级原子处于激发态与光场处于相干态的一般Jaynes－Cummings模型密度算符的精确解。
An exact solution is given of the generalized Jaynes-Cummings medel governed by the Milburn equation in the initial condition that the two-level atom is in excited state and field is in coherent atate. DUe to the existence of the intrinsic decoherence,the vibration of atomic inversfon and the mean numbers of photons of field decays with time evolution. In the limit22t/r>>1,the squeesing of the field amplitude does not present, but the antibunching effect of the field can be existed.
