耦合系数与时间有关的三能级原子同辐射场的相互作用

The Interaction of a Three Level Atom with the Radiation Field with the Time Dependent Atom Field Coupling

在级联型三能级原子与初始处于相干态的辐射场相互作用的ＪＣ模型基础上，本文研究相互作用耦合系数与时间有关的三能级原子与双模光场的相互作用。运用密度算符方法，借助数值计算，分析了该模型原子能级算符和平均光子数的性质。

In the paper we have studied a Jaynes Cummings Model (JCM) of interaction of a cascade three level atom with two model radiation field which the coupling coefficient is time dependent. By means of the method of density matrix, the properties of the average values of the atomic level operator, the average photon number of fields are discussed. More interesting results are analyzed.
