摘　　要：利用格子液体方法对■型三能级原子玻色-爱因斯坦凝聚体与单模压缩相干态光场相互作用系统的哈密顿量进行了改进,并且研究了■型三能级原子单模光场系统中光场压缩性质.结果表明:光场两正交分量交替呈现周期性压缩,其最大压缩深度由光场与原子间的相互作用强度和光场初始压缩因子决定,而压缩时间与光场的圆频率有关.The Hamiltonian operator of a system of E-type three-level atomic Bose-Einstein condensate interacting with single-mode squeezed coherent light field is improved in terms of the lattice-liquid model, and the squeezing properties of light field in this system are studied. The results show that two quadrature components of light can be squeezed periodically. The maximum depth of squeezing is determined by the interaction intensity between light field and atoms and the initial squeezing factor of light, and squeezing period is correlated with the frequency of the light field.
