摘　　要：目的研究玻色-爱因斯坦凝聚体与双模光场相互作用中光场的量子特性。方法在波戈留波夫近似下,求解系统的动力学方程。结果双模光场与波色-爱因斯坦凝聚体相互作用过程中,光场的两正交分量交替呈现周期性压缩现象,光子是聚束的。结论模间相关恒为非经典相关。Aim The purpose of this paper is to study the quantum properties of two-mode light fields interacting with Bose-Einstein condensate. Methods Bogoliubov＇s method is used to resolve the dynamic equations of the system. Results During the course of the interaction between two-mode light field and Bose-Einstein condensate, the two quadrature components of the light fields can be squeezed periodically, the photons produce bunching effect. Conclusion The correlation between the two modes always shows the non-classical correlation in the process of interaction between light fields and Bose-Einstein condensate.
