| Abstract: | Topological insulators, topological superconductors and photonic topological systems are of interest predominantly because of the robustness of their edge states. The mathematics behind this robustness, called K-theory, generally relies on some periodicity that enables the construction of some variation on momentum space. I will present a simple method to introduce a form of K-theory into any problem involving approximately compatible observables. This can be used to validate the robustness of the edge states on various model systems built on quasicrystals. | |
