Topological modes in photonic waveguide arrays
Gang Jiang, Siyuan Zhang, Weiwei Zhu +2
Periodic driving is a powerful tool to generate exotic topological phases without static counterparts, such as the anomalous chiral edge modes from bulk bands with zero Chern numbe…

Flatbands from Bound States in the Continuum for Orbital Angular Momentum Localization
Weiwei Zhu, Hongyu Zou, Yong Ge +7
A flatband material is a system characterized by energy bands with zero dispersion, allowing for the compact localization of wavefunctions in real space. This compact localization…
