Spectral topology and edge modes for one-dimensional non-Hermitian photonic crystals
Junshan Lin, Hai Zhang
This work investigates edge modes in non-Hermitian photonic crystals with broken spectral reciprocity. In such systems, the spectra of the underlying operators generally form close…

Mathematical Theory for Photonic Hall Effect in Honeycomb Photonic Crystals
Wei Li, Junshan Lin, Jiayu Qiu +1
In this work, we develop a mathematical theory for the photonic Hall effect and prove the existence of guided electromagnetic waves at the interface of two honeycomb photonic cryst…
