Phase Diagram of the $t$ -- $U$ -- $V_{1}$ -- $V_{2}$ Model at Quarter Filling

Satoshi Ejima, Florian Gebhard, Satoshi Nishimoto +1

We examine the ground-state properties of the one-dimensional Hubbard model at quarter filling with Coulomb interactions between nearest-neighbors $V_{1}$ and next-nearest neighbors…
