Abstract

After a decade of many claims to the opposite, there now is a growing consensus that generic disordered quantum wires, e.g. the XXZ-Heisenberg chain, do not exhibit many-body localization (MBL) - at least not in a strict sense within a reasonable window of disorder values W. Specifically, computational studies of short wires exhibit an extremely slow but unmistakable flow of physical observables ...
