Waveguiding in two-dimensional Floquet non-Abelian topological insulators
Yujie Zhou, Changsen Li, Xiumei Wang +1
Topological phases characterized by non-Abelian charges have garnered increasing attention recently. Although Floquet (periodic-driving) higher-order topological phases have been e…

Three-period evolution in a photonic Floquet extended Su-Schrieffer-Heeger waveguide array
Changsen Li, Yujie Zhou, Xiumei Wang +1
Periodic driving can induce the emergence of topological pi modes, and their superposition with zero modes leads to two-period dynamics. Introducing long-range couplings enables th…
