The NIST interatomic potential repository provides a collection of fitted interatomic potentials, either as fitted parameter values or numerical tables of the potential functions. [76] The OpenKIM [ 77 ] project also provides a repository of fitted potentials, along with collections of validation tests and a software framework for promoting ...
It includes a repository of interatomic potentials that are exhaustively tested with user-developed integrity tests, tools to help select among existing potentials and develop new ones, extensive metadata on potentials and their developers, and standard integration methods [3] for using interatomic potentials in major simulation codes.
Machine-learned interatomic potentials (MLIPs), or simply machine learning potentials (MLPs), are interatomic potentials constructed by machine learning programs. Beginning in the 1990s, researchers have employed such programs to construct interatomic potentials by mapping atomic structures to their potential energies.

Bond order potential is a class of empirical (analytical) interatomic potentials which is used in molecular dynamics and molecular statics simulations. Examples include the Tersoff potential, [1] the EDIP potential, the Brenner potential, [2] the Finnis–Sinclair potentials, [3] ReaxFF, [4] and the second-moment tight-binding potentials. [5]
In theoretical chemistry, the Buckingham potential is a formula proposed by Richard Buckingham which describes the Pauli exclusion principle and van der Waals energy for the interaction of two atoms that are not directly bonded as a function of the interatomic distance.
In northern Peru, the World Bank's business-lending arm is part owner of the Yanacocha gold mine, accused by impoverished farming communities of despoiling their land in pursuit of the precious ore. The bank and IFC have stepped up investments in projects deemed to have a high risk of serious and environment damage, including oil pipelines, mines and even coal-fired power plants, an ...
The Lennard-Jones potential is a simple model that still manages to describe the essential features of interactions between simple atoms and molecules: Two interacting particles repel each other at very close distance, attract each other at moderate distance, and eventually stop interacting at infinite distance, as shown in the Figure.
