Universal platform of point-gap topological phases from topological materials
Daichi Nakamura, Kazuya Inaka, Nobuyuki Okuma +1
Whereas point-gap topological phases are responsible for exceptional phenomena intrinsic to non-Hermitian systems, their realization in quantum materials is still elusive. Here we…

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…
