Fig. 3: 3D phonon spectra and the evolution of HWCCs.
From: Three-terminal Weyl complex with double surface arcs in a cubic lattice

3D representation of phonon spectra around the W1 (a) and W2 (b) nodes onto the (100) plane. The sum of HWCCs as a function of azimuthal angle θ for W1 (c) and W2 (d).
