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 Rashba-Holstein Model: A Quantum Monte Carlo Approach
Julián Faúndez, Rodrigo Alves Fontenele, Sebastião dos Anjos Sousa-Júnior +2
In this work, we investigate the impact of Rashba spin-orbit coupling (RSOC) on the formation of charge-density wave (CDW) and superconducting (SC) phases in the Holstein model on…
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, '…
