Non-Hermitian bulk-boundary correspondence and auxiliary generalized Brillouin zone theory
Zhesen Yang, Kai Zhang, Chen Fang +1
We provide a systematic and self-consistent method to calculate the generalized Brillouin Zone (GBZ) analytically in one dimensional non-Hermitian systems, which helps us to unders…

Correspondence between winding numbers and skin modes in non-hermitian systems
Kai Zhang, Zhesen Yang, Chen Fang
We establish exact relations between the winding of "energy" (eigenvalue of Hamiltonian) on the complex plane as momentum traverses the Brillouin zone with periodic boundary condit…
