Observation of non-Hermitian topology in a multi-terminal quantum Hall device
Kyrylo Ochkan, Raghav Chaturvedi, Viktor Könye +10
Quantum devices characterized by non-Hermitian topology are predicted to show highly robust and potentially useful properties, but realizing them has remained a daunting experiment…
Berezinskii-Kosterlitz-Thouless transition in the type-I Weyl semimetal PtBi
Arthur Veyrat, Valentin Labracherie, Dima L. Bashlakov +12
Symmetry breaking in topological matter has become in recent years a key concept in condensed matter physics to unveil novel electronic states. In this work, we predict that broken…
Polymorphic PtBi2: Growth, structure and superconducting properties
G. Shipunov, I. Kovalchuk, B. R. Piening +13
PtBi is a polymorphic system with interesting electronic properties. Here we report optimized crystal growth and structural characterization of pyrite-type and trigonal modific…
Disorder-induced coupling of Weyl nodes in WTe
Steffen Sykora, Johannes Schoop, Lukas Graf +7
The finite coupling between Weyl nodes due to residual disorder is investigated by magnetotransport studies in WTe. The anisotropic scattering of quasiparticles is evidenced fr…
Meta-magnetism of weakly-coupled antiferromagnetic topological insulators
Aoyu Tan, Valentin Labracherie, Narayan Kunchur +6
The magnetic properties of the van der Waals magnetic topological insulators MnBiTe and MnBiTe are investigated by magneto-transport measurements. We evidence that…
Suppression of scattering in quantum confined 2D-helical Dirac systems
Joseph Dufouleur, Emmanouil Xypakis, Bernd Büchner +2
Transport properties of disordered quantum confined helical Dirac systems are investigated in the large energy limit. As long as the 2D transport length is larger than the perimete…
