Two-dimensional Asymptotic Generalized Brillouin Zone Theory
Zeqi Xu, Bo Pang, Kai Zhang +1
In this work, we propose a theory on the two-dimensional non-Hermitian skin effect by resolving two representative minimal models. Specifically, we show that for any given non-Herm…
Edge theory of non-Hermitian skin modes in higher dimensions
Kai Zhang, Zhesen Yang, Kai Sun
In this paper, we establish an effective edge theory to characterize non-Hermitian edge-skin modes in higher dimensions. We begin by proposing a bulk projection criterion to straig…
Point-Gap Bound States in Non-Hermitian Systems
Zixi Fang, Chen Fang, Kai Zhang
In this paper, we systematically investigate the impurity-induced bound states in 1D non-Hermitian systems. By establishing an exact relationship between impurity potential and bou…
Loss-induced universal one-way transport in periodically driven systems
Chang Shu, Kai Zhang, Kai Sun
In this paper, we show that a periodically driven Aubry-André-Harper model with imbalanced on-site gain/loss supports universal one-way transport that is immune to impurities and i…
Geometry-dependent skin effect and anisotropic Bloch oscillations in a non-Hermitian optical lattice
Yi Qin, Kai Zhang, Linhu Li
The interplay between the non-Hermiticity and dimensionality gives rise to exotic characteristics in higher dimensions, with one representative phenomenon known as the geometry-dep…
Observation of dynamical degeneracy splitting for the non-Hermitian skin effect
Tuo Wan, Kai Zhang, Junkai Li +2
The non-Hermitian skin effect is a distinctive phenomenon in non-Hermitian systems, which manifests as the anomalous localization of bulk states at the boundary. To understand the…
