Quantum Impurities as Probes of Finite-Temperature Fluctuations in Two-Dimensional Bose Gases
Victor Velasco, Gabriele Spada, Giovanni Midei +2
Two-dimensional quantum gases provide a distinctive setting in which enhanced thermal fluctuations, finite-size effects, and two-body bound-state formation are intrinsically intert…
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…
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…
Nanoscale lattice heterostructure in high Tc superconductors
Annette Bussmann-Holder, Jürgen Haase, Hugo Keller +9
Low temperature superconductivity was known since 1957 to be described by BCS theory for an effective single band metals controlled by the density of states at the Fermi level, ver…
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…
Pairing amplification induced by nonadiabatic effects on the electron-phonon interaction throughout the BCS-BEC crossover
Victor Velasco, Giovanni Midei, Massimo Capone +1
Nonadiabatic effects in the electron-phonon coupling are important whenever the ratio between the phononic and the electronic energy scales, the adiabatic ratio, is non negligible.…
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…
