The complete topological classification of gapped states of matter in the presence of reflection symmetry
We obtain the complete classification of the reflection symmetric topological insulators and su-
perconductors using relative homotopy groups and exact sequences. The definition of topological
indices and corresponding generators are provided. Additionally, we address the issue of “subtle
instability” of the second descendant Z2 phase the presence of disorder.
