Non-abelian braiding of Weyl points

Abstract

We discuss the realization of non-abelian braiding of Weyl points in a two-dimensional crystal. This proposal is based on a refined homotopy characterization of band structures that goes beyond the current classification of crystalline topological phases of matter.
