opt-DDAP: Optimizable Density-Derived Atomic Point Charges via Automatic Differentiation.
Interatomic potentials which accurately describe long-range electrostatics require atom-centered charges. One such method to determine these atom-centered charges from density functional theory (DFT) calculations is the density-derived atomic point (DDAP) charge method. DDAP fits atom-centered Gaussians to the ground-s...
