Floquet higher-order topological insulators and superconductors with space-time symmetries
Yang Peng
Abstract
This work provides a complete classification of Floquet higher-order topological phases with an additional spacetime symmetry, which relates different positions in a system at different times. The classification results for such Floquet topological phases are connected to the ones for static topological phases with the corresponding spatial symmetry.
