Localization in the random XXZ quantum spin chain

We study the many-body localization (MBL) properties of the Heisenberg XXZ spin- $\frac 12$ chain in a random magnetic field. We prove that the system exhibits localization in any given energy interval at the bottom of the spectrum in a nontrivial region of the parameter space. This region, wh...
