Localization of fermions in coupled chains with identical disorder

Abstract

We study fermionic ladders with identical disorder along the leg direction. Following recent experiments we focus, in particular, on how an initial occupation imbalance evolves in time. By considering different initial states and different ladder geometries we conclude that in generic cases interchain coupling leads to a destruction of the imbalance over time, both for Anderson and for many-body localized systems.
