WebFloquet engineering offers a powerful approach to the generation of nonequilibrium topological phases with large topological invariants and hence a proliferation of topological edge modes. http://www-math.mit.edu/~stevenj/papers/HeAd19.pdf WebTopological insulators have unconventional gapless edge states where disorder-induced back-scattering is suppressed. In photonics, such edge states lead to unidirectional waveguides which are useful for integrated photonic circuitry. Cavity modes, lives yt
