Entropy Production in Mesoscopic Electronic Transport Beyond Weak-Coupling
Ivana R. A. C. Lucena, Caio H. Lewenkopf, Alexandre R. Rocha
We investigate the full statistics of entropy production in coherent mesoscopic conductors beyond the weak-coupling regime. Using the inside-outside perspective and the Landauer-Bü…
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-Rodríguez +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…
Quantum geometry and the electric magnetochiral anisotropy in noncentrosymmetric polar media
Pierpaolo Fontana, Victor Velasco, Chang Niu +6
The electric magnetochiral anisotropy is a nonreciprocal phenomenon accessible via second harmonic transport in noncentrosymmetric, time-reversal invariant materials, in which the…
Interacting Virtual Topological Phases in Defect-Rich 2D Materials
Felipe Crasto de Lima, Roberto H. Miwa, Caio Lewenkopf +1
We investigate the robustness of {\it virtual} topological states -- topological phases away from the Fermi energy -- against the electron-electron interaction and band filling. As…
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…
Phase transitions and scale invariance in topological Anderson insulators
Bryan D. Assunção, Gerson J. Ferreira, Caio H. Lewenkopf
We investigate disordered-driven transitions between trivial and topological insulator (TI) phases in two-dimensional (2D) systems. Our study primarily focuses on the BHZ model wit…
Structure-driven phase transitions in paracrystalline topological insulators
Victor Regis, Victor Velasco, Marcello B. Silva Neto +1
We study phase transitions driven by structural disorder in noncrystalline topological insulators. We introduce a procedural generation algorithm, the Perlin noise, typically used…
