Figure 1
The LL spectra at \(k_z=0\) with respect to the coupling measure g with \({\tilde{\alpha }}=0.05\) for both Model A (a), and for Model B (b). In (b), Labels “e” and “o” denote even and odd parity of states, and the red dots are the analytical solutions, except zero-energy ones, when \(\alpha =0\). (c, d) Illustrations of topological numbers of Weyl nodes, including chirality and vorticity, for Model A (c) and Model B (d). Chirality is identified by the outward or inward Berry flux, while vorticity is the directional winding number around a Weyl node.
