Description:
Author(s): Yong Xu, Fan Zhang, and Chuanwei Zhang We demonstrate that a Weyl point, widely examined in 3D Weyl semimetals and superfluids, can develop a pair of nondegenerate gapless spheres. Such a bouquet of two spheres is characterized by three distinct topological invariants of manifolds with full energy gaps, i.e., the Chern number of a 0D poi… [Phys. Rev.
