Figure 2

Flow of the Berry curvature vector field. Berry curvature of (a), band 6 and (b), band 7 in a cube centered at point H. All relevant features are highlighted and relate to Fig. 1. The size of the largest cone is 3500 \(\hbox {bohr}^2\). Cone size cutoff was performed as in the vicinity of monopole sources the magnitude of the Berry curvature is very large.
