Multi‐Fold Fan‐Shape Surface State Induced by an Isolated Weyl Phonon Beyond No‐Go Theorem
HH Fu, QB Liu, ZQ Wang, XF Yang - Advanced Science, 2023 - Wiley Online Library
Absence of any surface arc state has been regarded as the fundamental property of singular
Weyl points, because they are circumvented from the Nielsen‐Ninomiya no‐go theorem. In …

Network of topological nodal planes, multifold degeneracies, and Weyl points in CoSi
We showcase the importance of global band topology in a study of the Weyl semimetal CoSi

Hybrid nodal surface and nodal line phonons in solids
Phonons have provided an ideal platform for a variety of intriguing physical states, such as
non-Abelian braiding and the Haldane model. It is promising that phonons will realize the …
