| 摘 要： | 研究了Kerr介质腔中非关联双模热光场与V型三能级原子相互作用过程中的场关联特性.通过数值计算和图形分析,讨论了平均光子数、Kerr介质、失谐量以及耦合系数对场的关联特性的影响.结果发现:当V型三能级原子与两模光场发生相互作用时,非关联双模热光场将发生关联,且关联强度与耦合强度、失谐量和Kerr系数有关.当两模热光场和裸原子发生对称相互作用时,两模光场始终处于正关联;增加一模光场的平均光子数,两模光场的关联减弱;Kerr介质和失谐量的增加将削弱两模场的关联;当两模光场与原子发生不对称相互作用时,假设g1>g2,两模光场的关联特性在正关联和反关联之间交替出现.保持场一模的平均光子数不变,增加场另一模的平均光子数,反关联特性消失.

| Abstract: | The correlation properties of the uncorrelated two-mode thermal field during their interaction with V-type three-level atom in the Kerr medium cavity is studied.By numerical calculation and graphic analysis,the influences of the Kerr medium,the detuning,mean photon number and coupling constant on correlation property are discussed.The result shows that;when the V-type three-level atom is interacting with initial uncorrelated two-mode thermal field,the correlation of the two-mode field will take place and th... |
