Quantum-Hall physics and three dimensions
Johannes Gooth, Stanislaw Galeski, Tobias Meng
The discovery of the quantum Hall effect (QHE) in 1980 marked a turning point in condensed matter physics: given appropriate experimental conditions, the Hall conductivity σ_xy of…
Black hole mirages: electron lensing and Berry curvature effects in inhomogeneously tilted Weyl semimetals
Andreas Haller, Suraj Hegde, Chen Xu +3
We study electronic transport in Weyl semimetals with spatially varying nodal tilt profiles. We find that the flow of electrons can be guided precisely by judiciously chosen tilt p…
Gross-Neveu-Heisenberg criticality from expansion
Konstantinos Ladovrechis, Shouryya Ray, Tobias Meng +1
The Gross-Neveu-Heisenberg universality class describes a continuous quantum phase transition between a Dirac semimetal and an antiferromagnetic insulator. Such quantum critical po…
Engineering a pure Dirac regime in ZrTe
Jorge I. Facio, Elisabetta Nocerino, Ion Cosma Fulga +13
Real-world topological semimetals typically exhibit Dirac and Weyl nodes that coexist with trivial Fermi pockets. This tends to mask the physics of the relativistic quasiparticles.…
