WebbCalculating the Hessian for pairwise systems Molecular simulation systems are predominantly pairwise. That is, the potential energy for the simulation system is calculated as the sum of the interaction energies … Webbis a pair potential that usually is purely repulsive. In the original formulation [29] [30] the electron density function ρ ( r i j ) {\displaystyle \textstyle \rho (r_{ij})} was obtained from true atomic electron densities, and the embedding function was motivated from density-functional theory as the energy needed to 'embed' an atom into the electron density. .
