# C0, C2, C4, C, A, and B in [eV]
# delta, z0, eta, rho_cut, r_cut, and normal_cut in [Angstrom]
# lambda in [1/Angstrom]
#
# normal_cut is a parameter not present in the Wen paper, but specific to the
# LAMMPS implementation, which is used to find the 3 nearest neighbors of an
# atom to construct the normal.
