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…
Topological Phases in Fractals: Local Spin Chern Marker in the Sierpinski carpet Kane-Mele-Rashba Model
L. L. Lage, A. B. Félix, S. dos A. Sousa-Júnior +2
We study the spectral properties and local topology of the Kane-Mele-Rashba model on a Sierpinski Carpet (SC) fractal, constructed from a rectangular flake with an underlying honey…
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…
