Spatiotemporal Topological Phase Transition in non-Hermitian Photonic System
Zimeng Zeng, Zhuoyang Li, Jiayao Liu +2
While energy band topology in spatial photonic crystals (PCs) and momentum-band topology in temporal crystals have each served as powerful probes of topological phases in their res…

Dual Flat-Bands of Bound State in the Continuum and Radiative Mode via TE-TM Coupling
Jiayao Liu, Zimeng Zeng, Zhuoyang Li +2
A general symmetry-controlled mechanism is proposed for realizing dual flat-bands of bound state in the continuum (BIC) and its radiative counterpart in photonic crystal slabs. By…
