'Unhinging' the surfaces of higher-order topological insulators and superconductors

Abstract:

We show that the chiral Dirac and Majorana hinge modes in three-dimensional higher-order topological insulators (HOTIs) and superconductors (HOTSCs) can be gapped while preserving the protecting C2nT symmetry upon the introduction of non-Abelian surface topological order. In both cases, the topological order on a single side surface breaks time-reversal symmetry, but appears with its time-reversal conjugate on alternating sides in a C2nT preserving pattern. In the absence of the HOTI/HOTSC bu...
