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.
