【摘要】 研究了Kerr介质中对相干态光场与V型三能级原子依赖强度耦合相互作用的量子统计性质.对Cauchy-Schwartz不等式的研究表明:失谐量不为零(Ω1=Ω2≠0)时两模间的非经典相关程度有所增强,当初始场强ξ一定而两模场光子数差q增大时,场的非经典相关程度加强;q一定而ξ增大时,场的非经典相关程度减弱,Kerr效应使两模场的非经典相关性有所减弱.对二阶相干度的研究表明,第一模总呈现反聚束效应且Kerr效应对其影响相对较小,而第二模则聚束与反聚束效应交替出现,Kerr效应对g(222)的振荡幅度影响与q的大小有关.更多还原

【Abstract】 Quantum statistic properties of pair coherent states interacting with the V-type three-level atom via intensity-dependent coupling in Kerr medium are studied.The results show that when initial strength remains unchanged and photon difference q is increased,the non-classical coherent degree between the two-mode cavities is increased;when q remains unchanged and ξ is increased,the non-classical coherent degree is decreased;when the Kerr effect exist,the non-classical coherent degree is decreased.The results also show that,the second-order coherence degree of the cavity 1 shows g(2)11<1,the influence of Kerr effect is not evident.but the second-order coherence degree of the cavity 2 shows g(2)22<1 or g(2)22>1 alternatively;the amplitude of the g(2)22 change with q due to the Kerr effect.更多还原
