  • When dealing with many-body localization, one of the hardest tasks is the investigation in more than one spatial dimension and for bosons. We investigate the disorder driven localization of the two dimensional Bose-Hubbard model by evaluating the full low energy quasi-particle spectrum via a recently developed fluctuation operator expansion. For any considered (local) interaction we find a mobility edge that terminates at sufficiently large disorder strength, implying the existence of a many… CONTINUE READING
