Interaction driven polarization shift in the $t-V-V^{\prime }$ lattice fermion model at half filling: emergent Haldane phase

Balázs Hetényi

We study the $t-V-V^{\prime }$ model in one dimension at half-filling. It is known that for large enough $V$ fixed, as $V^{\prime }$ is varied, the system goes from a charge-density wave into a Lutt…
