Dear all,
The work done with using a negative dielectric in LAMMPS has been
accepted by Astronomy & Astrophysics and can be read on arXiv:
http://arxiv.org/abs/1503.04788
Best regards,
Andreas
congrats on the publication - as a bonus, you probably also
win the prize for greatest-degree-of-coarse-graining-in-an-MD-simulation,
at the comet scale.
Although there is also this: http://lammps.sandia.gov/pictures.html#jamming
for modeling sea ice with particles.
