玻色-爱因斯坦凝聚与Schrdinger猫态光场作用系统中原子信息熵压缩

Information entropy squeezing of the atom in system of Bose-Einstein condensate interacting with Schrodinger cat-state

运用量子信息熵理论,研究了玻色-爱因斯坦凝聚原子与Schr(o|¨)dinger猫态光场作用系统中,原子信息熵压缩随时间的演化特性。结果表明:该体系中Schr(o|¨)dinger猫态光场的两个相干态的相位角为★=π/2时,原子信息熵的压缩将随着光场强度、原子间及原子与场间的耦合系数的变化而呈现交替压缩现象。

The time evolution property of the atomic information entropy squeezing in Bose-Einstein condensate atom interacting, with the Schrodinger cat-states are studied by means of quantum theory. The results indicate that when phase angle φ is at π/2 between the two coherent states in the SchrSdinger cat state, atomic information entropy shows squeezing effects alternately with the variation of the intensity of optical field and coupling coefficients.
