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…
