Effects of next-nearest neighbor hopping on the pairing and critical temperatures of the attractive Hubbard model on a square lattice
Rodrigo A. Fontenele, Natanael C. Costa, Thereza Paiva +1
The attractive Hubbard model plays a paradigmatic role in the study of superconductivity (superfluidity) and has become directly realizable in ultracold atom experiments on optical…
Thermodynamic, magnetic and transport properties of the repulsive Hubbard model on the kagome lattice
Andressa R. Medeiros-Silva, Natanael C. Costa, Thereza Paiva
Over the past decades, magnetic frustration has been under intense debate due to its unusual properties. For instance, frustration in the kagome lattice suppresses long range spin…
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, '…
Signatures of metal to insulator crossover in the repulsive Fermi Hubbard model through static correlations
Sayantan Roy, Sameed Pervaiz, Thereza Paiva +1
Cold atom systems provide a rich platform to realize strongly interacting condensed matter systems, and recent progress in fluorescence imaging technique has enabled identification…
