Edge-selective extremal damping from topological heritage of dissipative Chern insulators
Suraj S. Hegde, Toni Ehmcke, Tobias Meng
One of the most important practical hallmarks of topological matter is the presence of topologically protected, exponentially localised edge states at interfaces of regions charact…
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.…
Steering Majorana braiding via skyrmion-vortex pairs: a scalable platform
Jonas Nothhelfer, Sebastián A. Díaz, Stephan Kessler +4
Majorana zero modes are quasiparticles that hold promise as building blocks for topological quantum computing. However, the litmus test for their detection, the observation of exot…
