Topological nodal-link phonons, three-fold, Dirac and six-fold nodal-point phonons in the insulator SiO2

By using first-principles calculations and symmetry analysis, we study the topologically nontrivial features of sextuple nodal-point phonons together with other kinds of topological phonons in realistic materials. The sextuple nodal-point phonons in all 230 space groups, enumerated in this paper, ar...
