A universal graph deep learning interatomic potential for the periodic table [PDF]

open access: yesNature Computational Science, 2022
Interatomic potentials (IAPs), which describe the potential energy surface of atoms, are a fundamental input for atomistic simulations. However, existing IAPs are either fitted to narrow chemistries or too inaccurate for general applications.
