Non-Hermitian topology in the quantum Hall effect of graphene
Burak Özer, Kyrylo Ochkan, Raghav Chaturvedi +12
Quantum Hall phases have recently emerged as a platform to investigate non-Hermitian topology in condensed-matter systems. This platform is particularly interesting due to its tuna…
kdotpy: theory on a lattice for simulating semiconductor band structures
Wouter Beugeling, Florian Bayer, Christian Berger +11
The software project kdotpy provides a Python application for simulating electronic band structures of semiconductor devices with theory on a lattice. T…
Non-Hermitian topology of transport in the quantum Hall phases in graphene
Raghav Chaturvedi, Viktor Könye, Ewelina M. Hankiewicz +2
It has recently been shown that signatures of non-Hermitian topology can be realized in a conventional quantum Hall device connected to multiple current sources. These signatures m…
Spectral asymmetry induces a re-entrant quantum Hall effect in a topological insulator
Li-Xian Wang, Wouter Beugeling, Fabian Schmitt +5
The band inversion of topological materials in three spatial dimensions is intimately connected to the parity anomaly of two-dimensional massless Dirac fermions. At finite magnetic…
