Tavis-Cummings模型中原子信息熵压缩的演化特性

Evolution Property of Atoms Information Entropy Squeezing in Tavis-Cummings Model

本文研究了Tavis-Cummings模型中,在共振时的原子信息熵压缩随时间的演化特性。在初始为相干光场和两原子分别为各种相干叠加态时,精确求解了二原子信息熵的各压缩分量,数值计算表明:该体系中原子信息熵的压缩将随二原子所处的初始状态、光场的强度、原子间及原子与场间的耦合系数的变化而变化.

This paper studies the evolution property of the atomic information entropy squeezing in the T-C model. When the field stays in coherent light field and two atoms stay in coherent superposition state initially we solve the components of atomic information entropy precisely and calculate entropy squeezing numerically. We obtain that the atomic information entropy squeezing will change with the variation of systemic initial state, the intensity of light field and coupling coefficients.
