The current understanding of topological insulators and their classical wave analogs, such as photonic topological insulators, is mainly based on topological band theory. Contrary to this, Scientists in China and Singapore experimentally showed photonic topological insulators based on glass-like amorphous phases, for which the bandstructure is ill-defined.
