研究了一位于高Q Kerr介质腔中的SU(2)相干态光场与Λ型三能级原子相互作用系统中，Kerr效应对三能级原子布居概率、光子统计分布、光场的模间相关性、Cauchy-Schwartz不等式以及光场差压缩的影响。结果表明，较强的Kerr效应可使原子Rabi振荡呈现明显的崩溃与回复现象，而使场的非经典相关程度减弱，但适当强度的Kerr效应可使光场差压缩程度明显增强。

The influences of Kerr effect on atomic populations,photon distribution,mode-correlation properties,Cauchy-Schwartz inequality and the difference squeezing of field in the system of a SU(2) coherent field interacting with a Λ-type three-level embedded in a high-Q cavity filled with Kerr medium are investigated.It is pointed out that the relatively strong Kerr effect can induce the atomic Rabi oscillation to exhibit explicit collapse-and-reclaim phenomenon,and will reduce nonclassical correlation extent of the field,the appropria...
