一维非Hermitian Anderson模型复本征值的正则间距

Regular Spacings of Complex Eigenvalues in the One-dimensional non-Hermitian Anderson Model

I. Ya. Goldsheid, B. A. Khoruzhenko

摘要:

证明了具有自平均势的非厄米特安德森(NHA)模型的非实本征值在一维上是规则分布的。我们在本文中介绍的自平均电位类是非常广泛的,特别是包括固定电位(概率为1),以及所有的准周期电位。应该强调的是,我们这里的方法比我们以前使用的方法简单得多。它使我们能够a)研究上述间距,b)建立具有自平均势的厄米特安德森模型的积分态密度的某些性质,以及c)获得(作为副产品)我们以前关于NHA模型的非实本征值的结果的更简单的证明。

英文摘要:

We prove that in dimension one the non-real eigenvalues of the non-Hermitian Anderson (NHA) model with a selfaveraging potential are regularly spaced. The class of selfaveraging potentials which we introduce in this paper is very wide and in particular includes stationary potentials (with probability one) as well as all quasi-periodic potentials. It should be emphasized that our approach here is much simpler than the one we used before. It allows us a) to investigate the above mentioned spacings, b) to establish certain properties of the integrated density of states of the Hermitian Anderson models with selfaveraging potentials, and c) to obtain (as a by-product) much simpler proofs of our previous results concerned with non-real eigenvalues of the NHA model.
