I can't even find the paper in question - DOI link in the article here doesn't even resolve. However, from the description of this model as "an interatomic forcefield", I'd guess this is more like a potential that can be used in classical molecular simulations. I.e. it's a highly refined and application-specific version of an EAM type model. This is a good jumping-off point for those: https://www.ctcms.nist.gov/potentials/ https://www.ctcms.nist.gov/potentials/
