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…

Observation of Erratic Non-Hermitian Skin Localization and Transport
Jia-Xin Zhong, Jee Woo Kim, Stefano Longhi +1
Localization is a pervasive phenomenon across physics, shaping transport from electrons in solids to light and sound in engineered media. In traditional settings, disorder strongly…

Experimentally Probing Non-Hermitian Spectral Transition and Eigenstate Skewness
Jia-Xin Zhong, Jeewoo Kim, Kai Chen +3
Non-Hermitian (NH) systems exhibit intricate spectral topology arising from complex-valued eigenenergies, with positive/negative imaginary parts representing gain/loss. Unlike the…
