Symmorphic and nonsymmorphic symmetries jointly-protected hourglass phonons
Baobing Zheng, Fangyang Zhan, Xiaozhi Wu +2
Hourglass dispersion is generally believed to be solely protected by nonsymmorphic symmetries, because these symmetries can introduce high-dimensional projective representations. H…
