摘　　要：利用格子液体方法改进了二能级原子玻色-爱因斯坦凝聚与二项式光场相互作用系统的哈密顿量,并且对系统中原子激光的压缩性质进行了研究。结果表明,原子激光具有量子Rabi振荡现象,且被周期性压缩,其量子Rabi振荡频率和最大压缩深度主要依赖于光场和原子间的相互作用强度。The Hamiltonian operator of a system of two-level atomic Bose-Einstein condensate interacting with binomial states field is improved in terms of the lattice-liquid model. The squeezing properties of atom laser from the system are studied. The results show that atom laser can be squeezed periodically and has quantum Rabi oscillation. The quantum Rabi frequency and the maximum depth of squeezing of atom laser depend heavily on the interaction intensity between light field and atoms.
