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…

Multifractal critical phase driven by coupling quasiperiodic systems to electromagnetic cavities
Thales F. Macedo, Julián Faúndez, Raimundo R. dos Santos +2
We theoretically investigate criticality and multifractal states in a one-dimensional Aubry-Andre-Harper model coupled to electromagnetic cavities. We focus on two specific cases w…

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…
