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…
