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…
Increasing superconducting by layering in the attractive Hubbard model
Rodrigo A. Fontenele, Natanael C. Costa, Thereza Paiva +1
The attractive Hubbard model has become a model readily realizable with ultracold atoms on optical lattices. However, the superconducting (superfluid) critical temperatures, '…
Multifractal critical phase driven by coupling quasiperiodic systems to electromagnetic cavities
Thales F. Macedo, Julián Faúndez, Raimundo R. dos Santos +2
We theoretically investigate criticality and multifractal states in a one-dimensional Aubry-Andre-Harper model coupled to electromagnetic cavities. We focus on two specific cases w…
