摘要
本文利用Bateman哈密顿系统中演化算符的因子化形式,讨论了当初始态为相干态时,此系统中的压缩性质.坐标算符的涨落表现出伴随着振荡的衰减行为,当时间足够长时,压缩将达至100％.
By using the factorization form of the evolution operator corresponding, to Bate-man Hamiltonian, the squeezing properties are discussed when the initial state is a coherent state. We conclude that the variance of coordinate operator will exhibit decaying behavior sccompanying with oscillations as time goes on and the squeezing can get to one hundred percent.
