Kane-Mele with a twist: Quasicrystalline higher-order topological insulators with fractional mass kinks
We establish an analytic low-energy theory describing higher-order topological insulator (HOTI) phases in quasicrystalline systems. We apply this to a model consisting of two stacked Haldane models with oppositely propagating edge modes, analogous to the Kane-Mele model, and with a 30^{∘} twist. We...
