The non-Hermitian skin effect is a unique phenomenon in which an extensive number of
eigenstates are localized at the boundaries of a non-Hermitian system. Recent studies show …

Multifractal analysis is a powerful tool for characterizing the localization properties of wave
functions. Despite its utility, this tool has been predominantly applied to disordered …

Although nonsymmorphic symmetry protects Z 4 topology for Hermitian systems, non-
Hermitian topological phenomena induced by such a unique topological structure remain …

The coexistence of edge states and skin effects provides the topologically protected
localized states at the corners of two-dimensional systems. In this paper, we realize such …

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 …
