Many-body localization for the random XXZ spin chain in fixed energy intervals
Alexander Elgart, Abel Klein
It is shown that the infinite random Heisenberg XXZ spin- chain exhibits slow propagation of information (logarithmic light cone), a key signature of many-body localizatio…

Localization phenomena in the random XXZ spin chain
Alexander Elgart, Abel Klein
It is shown that the infinite random Heisenberg XXZ spin- chain exhibits localization phenomena, such as spectral, eigenstate, and weak dynamical localization, in an arbit…

Slow propagation of information on the random XXZ quantum spin chain
Alexander Elgart, Abel Klein
The random XXZ quantum spin chain manifests localization (in the form of quasi-locality) in any fixed energy interval, as previously proved by the authors. In this article it is sh…
