Three-nodal surface phonons in solid-state materials: Theory and material realization

C. W. Xie, H. K. Yuan, Y. Liu +2

This year, Liu \textit{et al}. [Phys. Rev. B \textbf{104}, L041405 (2021)] proposed a new class of topological phonons (TPs; i.e., one-nodal surface (NS) phonons), which provides a…
