Random band matrix localization by scalar fluctuations

Probability 2022-06-15 v1

Abstract

We show the eigenvectors of a Gaussian random band matrix are localized when the band width is less than the 1/4 power of the matrix size. Our argument is essentially an optimized version of Schenker's proof of the 1/8 exponent.
