Quasiperiodicity-induced non-Hermitian skin effect from the breakdown of scale-free localization
Kazuma Saito, Ryo Okugawa, Kazuki Yokomizo +2
Non-reciprocal systems exhibit extreme sensitivity to boundary conditions, typically manifesting as the non-Hermitian skin effect (NHSE) under open boundaries. By bridging the boun…

Higher-winding phases in one-dimensional non-Hermitian topological superconductors
Yung-Yeh Chang, Xiang-Yu Li, Ken Shiozaki +1
Non-Hermitian topological superconductors provide a setting in which point-gap topology, non-Hermitian skin effects, and Majorana zero modes are strongly intertwined. In this work,…

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…
