a Structure of bulk Na3Bi. b Band dispersion of Na3Bi along the ky direction, for kx = 0 and kz = 0.28 π/c, where c is the out-of-plane lattice parameter. c Band dispersion of Na3Bi along the kz direction, for kx = ky = 0. The vertical lines indicate the position of the two Weyl points. The dashed lines represent the bandstructure without SOC.
