Eigenstate Thermalization Hypothesis for Wigner-type Matrices
Riabov, Volodymyr, László Erdős · arXiv (Cornell University) · 2024
We prove the Eigenstate Thermalization Hypothesis for general Wigner-type matrices in the bulk of the self-consistent spectrum, with optimal control on the fluctuations for observables of arbitrary rank. As the main technical ingredient, we prove rank-uniform optimal local laws for one and two resolvents of a Wigner-type matrix with regular observables.
