Aubry模型的Anderson转变区与能量的关系

RELATION BETWEEN THE ANDERSON TRANSITION ZONE AND ENERGY OF THE AUBRY MODEL

在已经证明一维无公度系统Aubry模型存在Anderson转变区的基础上,进一步研究转变区与能量的关系。数值结果表明,高能量区本征态的转变区处于势强度V较低的范围,低能量区本征态的转变区处于势强度V较高的范围。

On the basis of having proved that there exists the Anderson transition zone in the Aubry model of one-dimensional incommensurate systeme, we further study the relation between the Anderson transition zone and energy. Our numerical results indicate that the Anderson transition zone of the eigenstates in higher energy region is located in the range of lower values of the potential strength V, while, the Anderson transition zone of the eigenstates in lower energy region is located in the range of higher values of V.
