| Abstract: | When considering the interaction between atoms,the Hamitonian operator of a system of two-mode light field interacting with Bose-Einstein condensate(BEC) of V-type three-level atoms is suggested within the rotating-wave approximation and Bogoliubov approximation.The system's dynamical equations are solved.The influence of the interaction between atoms in the BEC on the quadrature squeezing properties of two-mode squeezed light interacting with atomic BEC is studied.Theresults show that the interaction between atoms in BEC shortens the period of the fluctuations of two quadrature components of light. |
