Anomalous Localization in Magnetically Doped Two-Dimensional Topological Insulators
Felippe Amorim, Washington F. dos Santos, Mauro S. Ferreira +2
Two-dimensional topological insulators (2DTIs) harbor spin-polarized edge states that are topologically protected by time-reversal symmetry against non-magnetic structural disorder…
Surface lone-pair polarization probed by quantum-geometric transport in tellurium
Nathanael N. Batista, Wendel S. Paz, Manuel Suárez-RodrÃguez +10
Stereochemically active lone pairs are ubiquitous microscopic sources of polarity in molecules and solids, but their collective behavior in crystals is often hidden by symmetry or…
Engineering Quantum Phases in Two Dimensions via Vacancy-Induced Electronic Reconstruction
Emmanuel V. C. Lopes, Felipe Crasto de Lima, Caio Lewenkopf +1
Topological phases of matter are commonly understood as emerging either from crystalline symmetry and intrinsic spin-orbit coupling or from disorder-driven electronic renormalizati…
Polar unidirectional magnetotransport in type tellurene from quantum geometry
Claudio Iacovelli, Pierpaolo Fontana, Victor Velasco +5
Unidirectional magnetoresistance, or electric magnetochiral anisotropy (eMChA), is a nonlinear magnetotransport phenomenon that arises in noncentrosymmetric conductors , where chan…
Gate-Tunable Giant Negative Magnetoresistance in Tellurene Driven by Quantum Geometry
Marcello B. Silva Neto, Chang Niu, Marcus V. O. Moutinho +5
Negative magnetoresistance in conventional two-dimensional electron gases is a well-known phenomenon, but its origin in complex and topological materials, especially those endowed…
Suppression of the Mott insulating phase in the particle-hole asymmetric Hubbard model
Mateus Marques, Bruno M. de Souza Melo, Alexandre R. Rocha +2
We explore the phase diagram of the Mott metal-insulator transition (MIT), focusing on the effects of particle-hole asymmetry (PHA) in the single-band Hubbard model. Our dynamical…
