Influence of the interaction between atoms on the squeezing properties of atomic lasers
原子间相互作用对原子激光压缩性质的影响

The influence of the interaction between atoms in Bose-Einstein condensate (BEC) on the squeezing properties of atomic lasers is studied under Bogoliubov approximation. The results show that the fluctuations of two quadrature components of the atomic laser can be squeezed and the interaction between atoms in BEC is disadvantageous to the squeeze of atomic lasers.
