Magic-free coexisting photonic and phononic moiré flat bands
Ziming Chen, Kaiyu Cui, Ning Wu +8
Moiré flat bands enhance localization and interactions through suppressed group velocity, but existing approaches largely target a single physical field because distinct excitation…

Arbitrary-order exceptional points in a nanomechanical cavity
Ning Wu, Kaiyu Cui, Ziming Chen +7
Higher-order exceptional points (EPs) govern non-Hermitian system dynamics through their enriched and sharpened spectral topology, yet the intrinsic topological fragility hinders r…
