Many-body Localization in Dipolar Systems

Phys Rev Lett. 2014 Dec 12;113(24):243002. doi: 10.1103/PhysRevLett.113.243002. Epub 2014 Dec 11.


Systems of strongly interacting dipoles offer an attractive platform to study many-body localized phases, owing to their long coherence times and strong interactions. We explore conditions under which such localized phases persist in the presence of power-law interactions and supplement our analytic treatment with numerical evidence of localized states in one dimension. We propose and analyze several experimental systems that can be used to observe and probe such states, including ultracold polar molecules and solid-state magnetic spin impurities.
