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 Schrodinger 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 Schrodinger 猫态光场的两个相干态的相位角为φ=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。
Abstract
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 Schrodinger cat state, atomic information entropy shows squeezing effects alternately with the variation of the intensity of optical field and coupling coefficients.
