Fractal photonic anomalous Floquet topological insulators to generate multiple quantum chiral edge states
Abstract Anomalous Floquet topological insulators with vanishing Chern numbers but supporting chiral edge modes are attracting more and more attention. Since the existing anomalous Floquet topological insulators usually support only one kind of chiral edge mode even at a large lattice size, they are...
