Figure 4. Symbols mark the location of one of the density of states peaks as a function of the slab thickness L_z at different chemical potential μ and magnetic field tilting angle θ_y or θ_x.

The lines are the asymptotic expression in the large L_z limit derived from the positions of and the Fermi velocity around the Weyl nodes in the bulk: for a magnetic field in the direction, and refer to Supplementary information for the expressions in the presence of a tilted magnetic field. While the peak positions typically show strong L_z dependence, notably, for particular ‘magic’ angles (blue circles), the peak positions asymptotically become nearly independent of sample thickness.
