3D phononic Stiefel–Whitney insulator: A case study of 3D 3,42T32-type carbon allotrope (3,42T32-CA)

The Stiefel–Whitney (SW) insulator, a specific example of a higher-order topological insulator, is supported by spatial and time-reversal (PT) symmetry. This system with a vanishing Chern number exhibits a topology that belongs to the second SW class. Although the identification of SW insulators has...
