The half-filled extended Hubbard model on a square lattice: Phase boundaries from determinant quantum Monte Carlo simulations
Sebastião dos Anjos Sousa-Júnior, Natanael C. Costa, Raimundo R. dos Santos
The extended Hubbard model (EHM) describes fermions on a lattice coupled through on-site, , and first-neighbor, , interactions. In the context of high- cuprates, antifer…
