The geometrically-averaged density of states calculated from the local Green's function as a measure of localization

Abstract

With the goal of measuring localization in disordered interacting systems, we examine the finite-size scaling of the geometrically-averaged density of states calculated from the local Green's function with finite energy resolution. Our results show that, unlike in a simple energy binning procedure, there is no limit in which the finite energy resolution is irrelevant.Comment: 2 pages, 1 figure; to be published in the proceedings of SCES '0
