2024 roadmap on 2D topological insulators
Bent Weber, Michael S Fuhrer, Xian-Lei Sheng +22
2D topological insulators promise novel approaches towards electronic, spintronic, and quantum device applications. This is owing to unique features of their electronic band struct…
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…
Conservation of chirality at a junction between two Weyl semimetals
Serguei Tchoumakov, Bogusz Bujnowski, Jonathan Noky +3
In Weyl semimetals the location of linear band crossings, the Weyl cones, is not bound to any high symmetry point of the Brillouin zone, unlike the Dirac nodes in graphene. This fl…
Quasi-quantized Hall response in bulk InAs
Rafał Wawrzyńczak, Stanislaw Galeski, Jonathan Noky +3
The quasi-quantized Hall effect (QQHE) is the three-dimensional (3D) counterpart of the integer quantum Hall effect (QHE),exhibited only by two-dimensional (2D) electron systems. I…
Imaging phonon-mediated hydrodynamic flow in WTe2
Uri Vool, Assaf Hamo, Georgios Varnavides +12
In the presence of interactions, electrons in condensed-matter systems can behave hydrodynamically, exhibiting phenomena associated with classical fluids, such as vortices and Pois…
(Quasi-)Quantization of the electrical, thermal, and thermoelectrical conductivities in two and three dimensions
Jonathan Noky, Johannes Gooth, Yan Sun +1
The quantum Hall effect in a 2D electron system expresses a topological invariant, leading to a quantized conductivity. The thermal Hall and thermoelectric Nernst conductances in t…
Evidence for an axionic charge density wave in the Weyl semimetal (TaSe4)2I
Johannes Gooth, Barry Bradlyn, Shashank Honnali +9
An axion insulator is a correlated topological phase, predicted to arise from the formation of a charge density wave in a Weyl semimetal. The accompanying sliding mode in the charg…
Anisotropic electrical and thermal magnetotransport in the magnetic semimetal GdPtBi
Clemens Schindler, Stanislaw Galeski, Walter Schnelle +14
The half-Heusler rare-earth intermetallic GdPtBi has recently gained attention due to peculiar magnetotransport phenomena that have been associated with the possible existence of W…
