Observation of photonic anomalous Floquet topological insulators

Vanishing Chern numbers usually mean that a system is topologically trivial, but this rule may be violated for periodically driven systems. Here, Maczewskyet al.report topologically protected edge modes in a periodically driven photonic lattice with all bands of zero Chern number.
