摘　　要：研究一个被克尔介质包围的两能级原子与单模辐射场通过k光子跃迁发生相互作用的系统,着重讨论了原子与辐射场通过三光子和四光子相互作用过程中,光场的熵压缩和原子布居数反转随时间演化的动力学特性,分析了克尔介质对光场熵压缩和原子布居数反转的影响,结果表明它们对克尔介质非线性作用非常敏感。The system under consideration consists of a two-level atom coupled an optical field in k-photon Jaynes-Cummings model with a Kerr medium. The time evolution of field entropy squeezing and population inversion of the atom for three and four-photon transitions was discussed. The influence of Kerr medium on field entropy squeezing and population inversion of the atom was also analyzed. The results show that the field entropy squeezing and population inversion of the atom are sensitive to effect of Kerr medium.
