Anomalous gapped boundaries between surface topological orders in higher-order topological insulators and superconductors with inversion symmetry
We show that the gapless boundary signatures—namely, chiral/helical hinge modes or localized zero modes—of three-dimensional higher-order topological insulators and superconductors with inversion symmetry can be gapped without symmetry breaking upon the introduction of non-Abelian surface topologica...
