(a) Electronic band structure of YMg. The band crossing points at the Γ–M and M–R paths are denoting as point A and point B, respectively. (b) Brillouin zone of the bulk for YMg. The green points and red circle denote the position of the triple nodal point and nodal line. (c) (101) surface spectrum and (d) (001) surface spectrum for YMg. In (c) and (d), the surface bands originating from nodal line and triple nodal point are indicated by the arrows. |
