    • Structured Weyl Points in Spin-Orbit Coupled Fermionic Superfluids 

      Xu, Yong; Zhang, Fan; Zhang, Chuanwei (American Physical Society, 2015-12-30)
      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 ...
