中文摘要：

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量子特性。讨论了两个原子与双模压缩真空场的相对耦合常数（R=g1/g2）和光场的初始压缩因子r对光场的压缩效应和光子的聚束与反聚束效应的影响。数值计算结果表明,光场量子涨落的震荡幅度、最大压缩深度、压缩时间及二阶相干度的震荡振幅与光场的初始压缩因子r的大小有关。两原子与双模光场的相对耦合常数R影响着光场量子涨落和二阶相干度的震荡规律,因而也影响着压缩时间、光场处于非经典态的时间及光子的反聚束程度,但对光场的压缩深度无明显影响。

英文摘要：

The quantum properties of light in the system of two different atoms interacting with two-mode squeezing vacuum field are studied. The effect of the relative coupling constant （ R = gl/g2） and initial squeezed parameter r on light squeezing effect and the photon bunching and antibunching are discussed. The numerical results show that vibration range of quantum fluctuation, the biggest squeezing depth and squeezing time and vibration amplitude of second-order coherence is affected by the initial squeezed parameter r. The variation of quantum fluctuation and second-order coherence versus time are affected by the relative coupling constant R. As a result, the squeezing time of quantum fluctuation, the time when light field is in non-classical states and the degree of photon antibunching are also affected by it, but to but it doesn＇t have obvious influence on light squeezing depth.
