Degenerate topological line surface phonons in quasi-1D double helix crystal SnIP

Abstract Degenerate points/lines in the band structures of crystals have become a staple of the growing number of topological materials. The bulk-boundary correspondence provides a relation between bulk topology and surface states. While line degeneracies of bulk excitations have been extensively ch...
