Real-space topology and charge order in the Haldane-Holstein Model
Sebastião dos Anjos Sousa-Júnior, Julián Faúndez, Tarik P. Cysne +2
We study the half-filled Haldane-Holstein model, where a paradigmatic Chern insulator is coupled to fully dynamical phonons, and provide an unbiased characterization of how retarde…
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…
Quantum percolation in honeycomb lattices under random spin-orbit coupling
W. S. Oliveira, Julián Faúndez, Welles Morgado
We investigate quantum percolation in a honeycomb lattice with site dilution and random spin-orbit coupling. Using exact diagonalization combined with finite-size scaling analysis,…
Spin-orbit coupled periodic Anderson model: Kondo-Dirac semimetal and orbital-selective antiferromagnetic semimetal
Sebastião dos Anjos Sousa-Júnior, Julián Faúndez, Rubem Mondaini
We investigate the periodic Anderson model composed of an itinerant -band and a strongly localized -band, featuring on-site electron-electron interactions in the -orbitals…
