Non-Hermitian topology of quantum spin-Hall systems to detect edge-state polarization

Raghav Chaturvedi, Ion Cosma Fulga, Jeroen van den Brink +1

We study the non-Hermitian topology of multi-terminal transport in a quantum spin-Hall device described by the Bernevig-Hughes-Zhang model. We show that breaking time-reversal symm…
