WebApr 7, 2024 · We identify all the symmetry classes where bulk line-gap topology induces boundary point-gap topology and establish the correspondence between their topological invariants. There also exist some symmetry classes where the Hermitian edge states remain stable, in the sense that even a point gap cannot open on the boundary.
