Crossover from Wannier-Stark localization to charge density waves for interacting spinless fermions in one dimension

Nair Aucar Boidi, Amnon Aharony, Ora Entin-Wohlman +2

We study spinless fermions on a finite chain with nearest-neighbor repulsion and in the presence of a Wannier-Stark linearly-varying electric field potential. In the absence of the…
