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 mechanical kink control and generation via phonons
Kai Qian, Nan Cheng, Francesco Serafin +4
Kinks (or domain walls) are localized transitions between distinct ground states associated with a topological invariant, and are central to many phenomena across physics, from con…
