From Bloch Oscillations to Many Body Localization in Clean Interacting Systems

Understand

In this work we demonstrate that non-random mechanisms that lead to single-particle localization may also lead to many-body localization, even in the absence of disorder.

• In particular, we consider interacting spins and fermions in the presence of a linear potential.
• In the non-interacting limit, these models show the well known Wannier-Stark localization.
• We analyze the fate of this localization in the presence of interactions.
