Anomalous gapped boundaries between surface topological orders in higher-order topological insulators and superconductors with inversion symmetry
Ming-Hao Li, Titus Neupert, S. A. Parameswaran +1
We show that the gapless boundary signatures - namely, chiral/helical hinge modes or localized zero modes - of three-dimensional higher-order topological insulators and superconduc…

`Unhinging' the surfaces of higher-order topological insulators and superconductors
Apoorv Tiwari, Ming-Hao Li, B. A. Bernevig +2
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…
