| 摘 要： | 研究了双模SU(1,1)相干态光场与V型三能级原子玻色-爱因斯坦凝聚(BEC)相互作用系统中光场的量子相关性质、振幅平方压缩效应和原子激光压缩效应。结果表明,双模SU(1,1)相干态光场各模的二阶相干度不随时间变化,光场各模光子是反聚束的,呈现非经典效应,光场两模相关性是非经典相关。光场具有周期性的振幅平方压缩效应,讨论了光场相关参数和原子相关参数对压缩深度、压缩频率的影响。双模原子激光不易压缩,压缩深度取决于光场初态。

| Abstract: | The quantum properties and amplitude-squared squeezing effects of light field are studied in the system of two-mode SU(1,1) coherent states interacting with Bose-Einstein Condensate of V-type three-level atoms,and the squeezing properties of atomic laser have also been discussed.The results show that the quantum correlation properties of light field keep invariant in the process of interaction between light field and atomic BEC,and the photons of each mode produce antibunching effect.The correlation between... |
