In terms of above review and the lattice-liquid model, we analyzed the Hamiltonian operator of a system of single-mode light field interacting with Bose-Einstein condensate (BEC) of two-level atoms developed in literature.

• 本文利用格子液体模型对周明等人的文献中给出的光场与二能级原子玻色-爱因斯坦凝聚体(BEC)相互作用系统的哈密顿量进行分析,表明其文献中对原子间相互作用部分的处理有不合理之处,从而对该哈密顿量作出了改进。
