| 摘 要： | 研究了具有不同偶极矩的两个原子与双模压缩真空场相互作用系统中光场的相干性质.讨论了两个原子与双模压缩真空场的相对耦合常量(R=g1/g2)和光场的初始压缩因子r对二阶相干度、光场的模间相关性、Cauchy-Schwartz不等式的影响.结果表明,光场的初始压缩因子较小时,光子的聚束效应和反聚束效应交替出现,且光场的模间相关程度较强.光场的初始压缩因子较大时,光子呈现聚束效应,且模间相关程度较弱.双原子的相对耦合常量R对二阶相干度、光场的模间相关性、Cauchy-Schwartz不等式的时间演化规律有影响,但不能改变光场模间相关的非经典性质.

| Abstract: | The coherence properties of light in the system of two different atoms interacting with two-mode squeezing vacuum field were studied.The effect of the relative coupling constant (R=g1/g2) and initial squeezed parameter on the second-order coherence,mode-correlation properties and Cauchu- Achwartz inequality were discussed.The results show that when the initial squeezed parameter is smaller,the phone bunching and antibunching are appearing by turns,and the dgree of mode-correlation property is more stronger.... |
