Local eigenvalue statistics for higher-rank Anderson models after Dietlein-Elgart
Abstract
We use the method of eigenvalue level spacing developed by Dietlein and Elgart (arXiv:1712.03925) to prove that the local eigenvalue statistics (LES) for the Anderson model on , with uniform higher-rank , single-site perturbations, is given by a Poisson point process with intensity measure , where is the density of states at energy in the region of localization near the spectral band edges. This improves the result of Hislop and Krishna (arXiv:1809.01236), who proved that the LES is a compound Poisson process with L\'evy measure supported on the set . Our proofs are an application of the ideas of Dieltein and Elgart to these higher-rank lattice models with two spectral band edges, and illustrate, in a simpler setting, the key steps of the proof of Dieltein and Elgart.
