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…
Superconducting properties of the three-dimensional Hofstadter-Hubbard model below the critical flux for Weyl points
Pierpaolo Fontana, Luca Lepori, Andrea Trombettoni
The three-dimensional Hofstadter model exhibits a critical rational flux at which Weyl points emerge in the single-particle spectrum. We study the superconducting regime of the mod…
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…
The Lattice Schwinger Model and Its Quantum Simulation
Joao C. Pinto Barros, Pierpaolo Fontana, Pasquale Sodano +1
In this chapter we review results on the lattice Schwinger model. In par-ticular, we show how the effect of the anomaly is reproduced on the lattice. We connect these results to re…
Renormalized dual basis for scalable simulations of 2+1D compact quantum electrodynamics
Marc Miranda-Riaza, Pierpaolo Fontana, Alessio Celi
The classical and quantum simulation of lattice gauge theories (LGTs) with Lie groups is hindered by the infinite-dimensional Hilbert space of gauge degrees of freedom. In a recent…
