Bulk-boundary correspondence in point-gap topological phases
Daichi Nakamura, Takumi Bessho, Masatoshi Sato
A striking feature of non-Hermitian systems is the presence of two different types of topology. One generalizes Hermitian topological phases, and the other is intrinsic to non-Herm…

Topological enhancement of non-normality in non-Hermitian skin effects
Yusuke O. Nakai, Nobuyuki Okuma, Daichi Nakamura +2
The non-Hermitian skin effects are representative phenomena intrinsic to non-Hermitian systems: the energy spectra and eigenstates under the open boundary condition (OBC) drastical…
