| 摘 要： | 在相干态表象中精确求解了无旋波近似的Jaynes-Cummings模型，并导出了相应的限制性条件．所求得的解析解与用微扰论求得的近似解比较，当微扰级数取无穷时所得结果一致．本文的方法能方便地推广到三能级系统的讨论．

| Abstract: | In this paper, a new approach of exact solution of Jaynes-Cummings model under rotationless wave approximation is proposed. The Jaynes-Cummings models of two-level system and three-level system have been investigated. Compared to some other approximate approaches, this approach can give not only an analytic exact solution, which agrees with others results but also a restraint condition, which is usefull for practical experiment. |
