(color online) Schematic band structure (with Fermi level shift slightly off the nodal points) of the three kinds of topological semimetals: Dirac semimetal (DSM), Weyl semimetal (WSM), and Nodal-line Semimetal (NLSM). The two massless Weyl nodes with distinct chirality in DSM are slightly displaced for clarity.
