| 摘 要： | 研究Kerr介质中，非旋波近似下，一个级联型三能级原子与光场相互作用的二阶相干度的时间演化，讨论了Kerr效应和虚光场效应对场的光子反聚束效应的影响.结果表明,虚光场的影响使系统出现量子噪声；而Kerr介质常量x、共振频率ω的增大及原子-场耦合系数g的减小都将降低原子对激发场的吸收效率，削弱受激辐射场的光子反聚束效应，其中以g的变化对系统的影响最为明显.

| Abstract: | We have studied the interaction between a cascacle three-level atom and the cavity field filled with Kerr medium by C-RWA. The influence of Kerr effect and virtual photon field on the photon anti-bunching is discussed. The results show that the quantum noise appears under C-RWA; the increase of x and ω or the decrease of g leads to the decrease of absorbance of atom and the reduction of photon antibunching;especially,the interaction is influenced obviouslly by g. |
