"Potential" Problems
These are some potential files we used in our simulations of molecular structures. Please note that since we use a variety of codes, the potential files will be in a variety of foremats. The most common codes used by our group are LAMMPS ( and ParaDyne) and MD++. These codes use different file formats for EAM potentials, so all files should specify which file format. We will also try to provide a reference describing the potential.
