具有奇异随机势的连续Anderson模型局部化的综合证明

A comprehensive proof of localization for continuous Anderson models with singular random potentials

François Germinet, Abel Klein

摘要:

本文研究了具有非退化单点概率分布的连续Anderson Hamilton算子,其中单点概率分布不满足任何正则性条件。我们证明了谱底部存在一种强形式的局域化,其中包括具有有限重数本征值的安德森局域化(具有指数衰减本征函数的纯点谱)、动力学局域化(在时间演化下没有波包的传播)、本征函数相关性的衰减以及费米投影的衰减。我们还证明了积分态密度在谱底的log-H”older连续性。

英文摘要:

We study continuous Anderson Hamiltonians with non-degenerate single site probability distribution of bounded support, without any regularity condition on the single site probability distribution. We prove the existence of a strong form of localization at the bottom of the spectrum, which includes Anderson localization (pure point spectrum with exponentially decaying eigenfunctions) with finite multiplicity of eigenvalues, dynamical localization (no spreading of wave packets under the time evolution), decay of eigenfunctions correlations, and decay of the Fermi projections. We also prove log-H\" older continuity of the integrated density of states at the bottom of the spectrum.
