Non-Hermitian topological devices with Chern insulators
Kyrylo Ochkan, Michael Wissmann, Louis Veyrat +9
Multi-terminal topological devices are a new generation of electronic devices with quantized properties robust against imperfections. In magnetic topological insulators, dissipatio…
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…
Non-Hermitian topological ohmmeter
Viktor Könye, Kyrylo Ochkan, Anastasiia Chyzhykova +4
Measuring large electrical resistances forms an essential part of common applications such as insulation testing, but suffers from a fundamental problem: the larger the resistance,…
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…
