Description:
Author(s): Bohm-Jung Yang, Takahiro Morimoto, and Akira Furusaki In general, the stability of a band crossing point indicates the presence of a quantized topological number associated with it. In particular, the recent discovery of three-dimensional Dirac semimetals in Na 3 Bi and Cd 3 As 2 demonstrates that a Dirac point with fourfold degeneracy can be stable as long… [Phys. Rev.
