The thermopower properties of interacting systems
M. A. Habitzreuter, Willdauany C. de Freitas da Silva, Rodrigo A. Fontenele +2
The Seebeck coefficient quantifies the voltage generated across a material in response to a temperature gradient. Recent studies have shown that strong electronic correlations can…
The two-dimensional optical Su-Schrieffer-Heeger model: ground state and thermodynamic properties
Jadson L. Portela e Silva, Gabriel Rein, Sebastião dos A. Sousa-Júnior +2
We investigate the two-dimensional optical Su-Schrieffer-Heeger (SSH) model, in which the electron hopping amplitude is modulated by the difference between neighboring phonon coord…
Finite temperatures and flat bands: the Hubbard model on three-dimensional Lieb lattices
Lucas O. Lima, Julián Faúndez, Natanael C. Costa +1
We investigate some thermodynamic and magnetic properties of the Hubbard model on two three-dimensional extensions of the Lieb lattice: the perovskite Lieb lattice (PLL) and the la…
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…
