Many body localization with long range interactions

Understand

Many body localization (MBL) has emerged as a powerful paradigm for understanding non-equilibrium quantum dynamics.

• Folklore based on perturbative arguments holds that MBL only arises in systems with short range interactions.
• Here we advance non-perturbative arguments indicating that MBL can arise in systems with long range (Coulomb) interactions.
• In particular, we show using bosonization that MBL can arise in one dimensional systems with ~ r interactions, a problem that exhibits charge confinement.
