Multifractal statistics of non-Hermitian skin effect on the Cayley tree
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 …

Non-Hermitian skin effect protected by glide symmetry
S Ishikawa, T Yoshida - Physical Review B, 2024 - APS
Although nonsymmorphic symmetry protects Z 4 topology for Hermitian systems, non-
Hermitian topological phenomena induced by such a unique topological structure remain …

Hybrid Higher-Order Skin Topological Modes in the Two-Dimensional Su–Schrieffer–Heeger Model with Nonreciprocal Hoppings
H Wakao - Journal of the Physical Society of Japan, 2024 - journals.jps.jp
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 …

Exceptional Second-Order Topological Insulators
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 …
