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…

Unveiling non-Hermitian band structures with non-Bloch supercells
Jia-Xin Zhong, Jing Lin, Kai Chen +3
Real-valued band structures are foundational to analyzing periodic systems within the Hermitian description and have been experimentally well-established over recent decades. In co…
