Phase Transitions and Generalized Biorthogonal Polarization in Non-Hermitian Systems
Elisabet Edvardsson, Flore K. Kunst, Tsuneya Yoshida +1
Non-Hermitian (NH) Hamiltonians can be used to describe dissipative systems, and are currently intensively studied in the context of topology. A salient difference between Hermitia…

Dissipative analog of four-dimensional quantum Hall physics
Fanny Terrier, Flore K. Kunst
Four-dimensional quantum Hall (QH) models usually rely on synthetic dimensions for their simulation in experiment. Here, we study a QH system which features a nontrivial configurat…
