Inferring stealthy hyperuniform correlations from quantum transport
Natanael C. Costa, Mauro S. Ferreira, Caio Lewenkopf +4
Stealthy hyperuniform disordered systems exhibit strongly suppressed long-wavelength fluctuations, producing correlated disorder with unusual consequences for wave propagation. A c…
Inverse determination of light-matter coupling in disordered systems from transmittance spectra
Thales F. Macedo, Julián Faúndez, Julián Faúndez +6
We investigate quantum inverse problems in one-dimensional (1D) electronic disordered systems strongly coupled to optical cavities. More specifically, we consider the Anderson and…
The thermopower properties of interacting systems
M. A. Habitzreuter, Willdauany C. de Freitas da Silva, Rodrigo A. Fontenele +2
The quest for efficient devices has fueled research in thermoelectric materials. In these materials, the goal is to maximize the Figure of Merit . One of the components of this…
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…
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…
