Anderson型模型特征值的简单性

Simplicity of eigenvalues in Anderson-type models

Sergey Naboko, Roger Nichols, Günter Stolz

摘要:

我们几乎肯定简单的特征值的几个模型的安德森型随机薛定谔算子,扩展方法介绍了西蒙的离散安德森模型。这些方法在整个频谱中工作,并且不限于本地化机制。我们建立了一般的标准,简单的特征值,可以被解释为单独排除当地和全球的对称性的情况下,分别。该准则适用于安德森模型与矩阵值的潜力,以及与单站的潜力支持在一个有限的盒子。

英文摘要:

We show almost sure simplicity of eigenvalues for several models of Anderson-type random Schrödinger operators, extending methods introduced by Simon for the discrete Anderson model. These methods work throughout the spectrum and are not restricted to the localization regime. We establish general criteria for the simplicity of eigenvalues which can be interpreted as separately excluding the absence of local and global symmetries, respectively. The criteria are applied to Anderson models with matrix-valued potential as well as with single-site potentials supported on a finite box.
