Query: Many-body localization in one dimensional optical lattice with speckle
  disorder   The many-body localization transition for Heisenberg spin chain with a
speckle disorder is studied. Such a model is equivalent to a system of spinless
fermions in an optical lattice with an additional speckle field. Our numerical
results show that the many-body localization transition in speckle disorder
falls within the same universality class as the transition in an uncorrelated
random disorder, in contrast to the quasiperiodic potential typically studied
in experiments. This hints at possibilities of experimental studies of the role
of rare Griffiths regions and of the interplay of ergodic and localized grains
at the many-body localization transition. Moreover, the speckle potential
allows one to study the role of correlations in disorder on the transition. We
study both spectral and dynamical properties of the system focusing on
observables that are sensitive to the disorder type and its correlations. In
particular, distributions of local imbalance at long times provide an
experimentally available tool that reveals the presence of small ergodic grains
even deep in the many-body localized phase in a correlated speckle disorder.
