Real-space topology and charge order in the Haldane-Holstein Model
Sebastião dos Anjos Sousa-Júnior, Julián Faúndez, Tarik P. Cysne +2
We study the half-filled Haldane-Holstein model, where a paradigmatic Chern insulator is coupled to fully dynamical phonons, and provide an unbiased characterization of how retarde…
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…
Magnetic impurities in a charge-ordered background
Sebastião dos Anjos Sousa-Júnior, Raimundo R. dos Santos, Natanael C. Costa
We investigate how magnetic impurities may affect a system exhibiting charge-density wave (CDW) in its ground state. We consider a disordered Hubbard-Holstein model with a homogene…
Magnetism and metal-insulator transitions in the Rashba-Hubbard model
Welberth Kennedy, Sebastião dos Anjos Sousa Júnior, Natanael C. Costa +1
The nature of metal-insulator and magnetic transitions is still a subject under intense debate in condensed matter physics. Amongst the many possible mechanisms, the interplay betw…
