Quantum Hall Effect without Chern Bands
Benjamin Michen, Jan Carl Budich
The quantum Hall effect was originally observed in a two-dimensional electron gas forming Landau levels when exposed to a strong perpendicular magnetic field and was later generali…

Mesoscopic transport signatures of disorder-induced non-Hermitian phases
Benjamin Michen, Jan Carl Budich
We investigate the impact on basic quantum transport properties of disorder-induced exceptional points (EPs) that emerge in a disorder-averaged Green's function description of two-…

Exceptional Non-Hermitian Phases in Disordered Quantum Wires
Benjamin Michen, Tommaso Micallo, Jan Carl Budich
We demonstrate the occurrence of nodal non-Hermitian (NH) phases featuring exceptional degeneracies in chiral-symmetric disordered quantum wires, where NH physics naturally arises…
