Boundary topological insulators and superconductors of Altland-Zirnbauer tenfold classes
In a class of systems, there are gapped boundary-localized states described by a boundary
Hamiltonian. The topological classification of gapped boundary Hamiltonians can lead to the …

Family of third-order topological insulators from Su-Schrieffer-Heeger stacking
We construct a family of chiral symmetry-protected third-order topological insulators by
stacking Su-Schrieffer-Heeger (SSH) chains and provide a unified topological …

Surface-dependent Majorana vortex phases in topological crystalline insulators
The topological crystalline insulator SnTe exhibits two types of surface Dirac cones: one
located at non-time-reversal-invariant momenta on the (001) and (110) surfaces, and the …
