DOI: 10.1088/1742-5468/abda26
Abstract: We present a detailed account of a first-order localization transition in the discrete nonlinear Schrödinger equation, where the localized phase is associated to the high energy region in parameter space. We show that, due to… read more here.

Abstract: Translationally invariant flatband Hamiltonians with interactions lead to a many-body localization transition. Our models are obtained from single particle lattices hosting a mix of flat and dispersive bands, and equipped with fine-tuned two–body interactions. Fine-tuning… read more here.

DOI: 10.1103/physrevb.96.104201
Abstract: Thermal and many-body localized phases are separated by a dynamical phase transition of a new kind. We analyze the distribution of off-diagonal matrix elements of local operators across this transition in two different models of… read more here.
