Abstract

We prove that in strongly disordered, interacting, quantum chains, the conductance of a chain of length LL vanishes faster than 1/L1/L. This means that transport is anomalous in such chains. This phenomenon was first claimed in \cite{Basko2006,gornyi2005interacting} and a pioneering treatment appeared in \cite{Imbrie2016a}
