英文摘要
Density functional theory (DFT) cannot describe the dispersion interaction. Empirical dispersion corrections are unreliable for newer systems. In this work, we propose a new method to compute the dispersion interaction based on the local response approximation (LRD). Our goal is a method that accurately describes weak interactions with a low computational cost. The LRD method gives dispersion coefficients between atoms in a molecule as a functional of the ground-state electron density. A generalization to the multicenter interactions and the self-consistent field implementation enable accurate quantum chemical calculations of complex molecular assemblies.
