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…
Artificial event horizons in Weyl semimetal heterostructures and their non-equilibrium signatures
Christophe De Beule, Solofo Groenendijk, Tobias Meng +1
We investigate transport in type-I/type-II Weyl semi\-metal heterostructures that realize effective black- or white-hole event horizons. We provide an exact solution to the scatter…
Hawking fragmentation and Hawking attenuation in Weyl semimetals
Daniel Sabsovich, Paul Wunderlich, Victor Fleurov +3
We study black and white hole analogues in Weyl semimetals with inhomogenous nodal tilts. We study how the presence of a microscopic lattice, giving rise to low-energy fermion doub…
Universal Hall conductance scaling in non-Hermitian Chern insulators
Solofo Groenendijk, Thomas L. Schmidt, Tobias Meng
We investigate the Hall conductance of a two-dimensional Chern insulator coupled to an environment causing gain and loss. Introducing a biorthogonal linear response theory, we show…
