# BKS library - rigid ion potentials for silica | ||
# | ||
# Reference: | ||
# B.W.H. van Beest et al, Phys. Rev. Lett., 64, 1955 (1990) | ||
# | ||
# NOTE: Because of the large C6 terms (which are unphysical | ||
# and the short cutoff given in the paper, there will | ||
# be lots of problems associated with potential | ||
# discontinuities if using this library. It should also | ||
# be noted that the SiO2 potential is known to give the | ||
# incorrect ground state polymorph for silica. You have | ||
# been warned! | ||
