【摘要】 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。更多还原

【Abstract】 The time evolution property of the atomic information entropy squeezing in Bose-Einstein condensate atom interacting with the Schr(o|¨)dinger cat-states are studied by means of quantum theory.The results indicate that when phase angle φ is atπ/2 between the two coherent states in the Schrdinger cat state,atomic information entropy shows squeezing effects alternately with the variation of the intensity of optical field and coupling coefficients.更多还原
