Interatomic Potentials: LJ and EAM

This lecture covers interatomic potentials, describing the energy and stability of atoms based on their chemical nature and interactions. Various empirical forms, such as the Lennard-Jones (LJ) potential and Embedded Atom Model (EAM), are discussed. The lecture explores the fitting of potentials to match material properties, including cohesive energy and lattice parameters, and the challenges of empirical potential fitting.
