Figure 7
Imaginary part of the dielectric function with the explicit contribution of the W1 and W2 Weyl nodes (Total: black line; W1: red dashed line, and W2: blue dot-dashed line) for (a) TaAs, (b) TaP, (c) NbAs, and (d) NbP. The total spectrum contains W1 and W2 contributions as well as those of the trivial points.
