The extended Hubbard model on a honeycomb lattice
Welberth Kennedy, Sebastião dos Anjos Sousa-Júnior, Natanael C. Costa +1
The lack of both nesting and a van Hove singularity at half filling, together with the presence of Dirac cones makes the honeycomb lattice a special laboratory to explore strongly…

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…
