[lammps-users] electron force field (eFF)

HI all - another cool force field added to LAMMPS today,
due to the hard work of Andres Jaramillo-Botero at CalTech.

This is the Goddard group's electron force field (eFF) which can model
light Z materials with their electrons in various excited states.

See http://lammps.sandia.gov/doc/pair_eff.html
and the 6 Sept 2010 patch for details.

This is the first model in LAMMPS actually suitable for
modeling electrons directly - my quantum friends will
be so impressed!
