　　摘要：

　　Dirac points were originally discovered in the electronic band structures of semimetals and recently engineered in the classical energy spectra of artificial crystals, exhibiting fascinating physics that entangles symmetry, topology, and interaction.  In this talk, I will discuss our theoretical prediction of protected Dirac point nodes in the Bogoliubov-de Gennes spectra of superconductors, in which the established order parameters are even (odd) under mirror reflection (special inversion). Under further symmetry breaking, the Dirac superconductor can turn into a Weyl, topological, or nodal-line superconductor.  I will also show the experimental evidences of such Dirac nodes in the recently confirmed nematic superconductors (e.g. metal-intercalated Bi2Se3) and suggest some future experiments to detect the smoking-gun signatures of Dirac nodes.
