摘要 研究了在充有Kerr-介质腔中一个二能级原子通过双光子过程与一单模腔场相互作用的动力学问题,阐明了适当组合原子-场的失谐δ和非线性参数χ(3)可得到周期性的动力学现象.考虑了量子系统的统计性质,给出了光子数分布和原子反转,分析了场的纯度. Investigated the dynamics of a two-level atom in a cavity filled with a nonlinear medium by two-photon process, elucidated that the atom-field detuning δ and the nonlinear parameter X may be combined to yield a periodic dynamics, showed the statistic property of this quantum system, and analyzed the atomic inversion and the field purity.
