Floquet higher-order topological insulators and superconductors with space-time symmetries

Floquet higher-order topological insulators (HOTIs) and superconductors (SCs) with an order-2 space-time symmetry or antisymmetry are classified. This is achieved by considering unitary loops, whose nontrivial topology leads to the anomalous Floquet topological phases, subject to a space-time symmet...
