| 摘 要： | 本文精确求解了一个二能级原子与一个多模辐射场相互作用的动力学问题．文中没有用到旋转波近似和偶极近似,而是运用相干态展开技术,求得了相互作用过程中原子的上下两能级的粒子数随时间的变化情况,并讨论了系统中光子数随频率的分布．计算机的模拟计算给出了一些有意义的结果．

| Abstract: | 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. |
