We illustrate a procedure that defines and converts non-Abelian charges of Weyl nodes via braid phase factors, which arise upon exchange inside the reciprocal momentum space. This phenomenon derives from intrinsic symmetry properties of topological materials, which are increasingly becoming available due to recent cataloguing insights. Specifically, we demonstrate that band nodes in systems with $C_2T$ symmetry exhibit such braiding properties, requiring no particular fine-tuning. We further… Expand

Non-Abelian band topology in noninteracting metals
TLDR
Non-Abelian topological charges that characterize line nodes inside the momentum space of crystalline metals with space-time inversion and weak spin-orbit coupling are introduced and it is shown that these are quaternion charges, similar to those describing disclinations in biaxial nematics.
