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…
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…
Strain-tunable anomalous Hall effect in hexagonal MnTe
Zhaoyu Liu, Sijie Xu, Jonathan M. DeStefano +15
The ability to control and manipulate time-reversal () symmetry-breaking phases with near-zero net magnetization is a sought-after goal in spintronic devices. The recently disco…
Photodynamic melting of phase-reversed charge stripes and enhanced condensation
Jianhao Sun, Richard T. Scalettar, Rubem Mondaini
The interplay between charge stripes and pairing has long been a subject of scrutiny in a broad class of unconventional superconductors, as in some cases it is unclear whether this…
Weyl semimetallic, Néel, spiral, and vortex states in the Rashba-Hubbard model
Sebastião dos Anjos Sousa-Júnior, Rubem Mondaini
We investigate the evolution of magnetic phases in the Hubbard model under strong Rashba spin-orbit coupling on a square lattice. By using Lanczos exact diagonalization and determi…
Electronic interactions in a vacancy-engineered honeycomb lattice: Transition from a nodal-line semimetal to a magnetic insulator
Andressa R. Medeiros-Silva, Mariana Malard, Rodrigo G. Pereira +1
Nodal-line semimetals (NLSMs) harbor a variety of novel physical properties owing to the particularities of the band degeneracies that characterize the spectrum of these materials.…
