Marginal Anderson localization and many-body delocalization
We consider d-dimensional systems which are localized in the absence of interactions, but
whose single-particle localization length diverges near a discrete set of (single-particle) …

Extended states in disordered systems: role of off-diagonal correlations
We study one-dimensional systems with random diagonal disorder but off-diagonal short-
range correlations imposed by structural constrains. We find that these correlations generate …
