Quasiperiodicity-induced bulk localization with self similarity in non-Hermitian systems
Yu-Peng Wang, Chuo-Kai Chang, Ryo Okugawa +1
We analyze the localization behavior in a non-Hermitian system subject to a quasiperiodic onsite potential. We characterize localization transitions using multiple quantitative ind…

Exceptional second-order topological insulators
Yutaro Tanaka, Daichi Nakamura, Ryo Okugawa +1
Point-gap topological phases of non-Hermitian systems exhibit exotic boundary states that have no counterparts in Hermitian systems. Here, we develop classification of second-order…
