Observation of Universal Spectral Moments and the Dynamic Dispersive-to-Proliferative Transition

Jia-Xin Zhong, Chang Shu, Nan Cheng +4

In non-Hermitian systems, spectra can be maximally boundary-sensitive, yet bulk physics need not be. Here we experimentally show that spectral moments provide boundary-robust bulk…

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…

Dynamical Degeneracy Splitting and Directional Invisibility in Non-Hermitian Systems

Kai Zhang, Chen Fang, Zhesen Yang

In this paper, we introduce the concept of dynamical degeneracy splitting to describe the anisotropic decay behaviors in non-Hermitian systems. We demonstrate that systems with dyn…
