From Bloch oscillations to many-body localization in clean interacting systems
E van Nieuwenburg, Y Baum… - Proceedings of the …, 2019 - National Acad Sciences
In this work we demonstrate that nonrandom mechanisms that lead to single-particle
localization may also lead to many-body localization, even in the absence of disorder. In …
