摘　　要：研究了被类Kerr介质包围的双光子Jagnes—Cummings模型中原子能级占有几率随时间演化的规律,讨论了类Kerr介质对原子能级占有几率的影响.结果表明,原子能级占有几率较强地依赖于光场与非线性介质的耦合程度,耦合愈强,原子在初态的布居捕获愈高.In this paper,the time evolution of the atomic level occupation probabilities with an additional Kerr-like medium are studied,the influence of Kerr-like medium on the atomic level occupation probabili-ties have been discussed. Our results indicate the atomic level occupation probabilities strongly depends on the coupling extent of the field with the nonline medium,the stronger the coupling,the more high the population capture on initial state of the atom.
