随机带状矩阵

Random band matrices

Paul Bourgade

摘要:

本文综述了近年来有关随机带状矩阵谱的数学结果。我们首先暴露的Erd{ \H o}的Schlein-丘动态方法,其应用到维格纳矩阵,并扩展到其他平均场模型。然后,我们介绍了随机带状矩阵和安德森过渡的问题。最后,我们描述了一种方法来获得离域性和普遍性在一些稀疏制度,突出量子唯一遍历的作用。

英文摘要:

We survey recent mathematical results about the spectrum of random band matrices. We start by exposing the Erd{\H o}s-Schlein-Yau dynamic approach, its application to Wigner matrices, and extension to other mean-field models. We then introduce random band matrices and the problem of their Anderson transition. We finally describe a method to obtain delocalization and universality in some sparse regimes, highlighting the role of quantum unique ergodicity.
