An experimental scheme for determining the Berry phase in two-dimensional quantum materials with a flat band
Li-Li Ye, Cheng-Zhen Wang, Ying-Cheng Lai
Experimentally feasible methods to determine the Berry phase, a fundamental quantity characterizing a quantum material, are often needed in applications. We develop an approach to…

Bound states in the continuum induced via local symmetries in complex structures
Cheng-Zhen Wang, Ulrich Kuhl, Adin Dowling +2
Bound states in the continuum (BICs) defy conventional wisdom that assumes a spectral separation between propagating waves, that carry energy away, and spatially localized waves co…
