摘要
利用量子么正变换引起拓扑项的可移性,求出了一维无限深运动边界方势阱在压缩变换中出现的微扰项在一级近似下对Berry相因子的贡献。
Using the removability of the topological term induced by quantum unitary transformation,this paper derives the Berry phase of the perturbation term originating from the squeezing transformation of the one-dimensional infinite deep square potentiaI trough with the motive boundary under one-order approximation.
