Category:ACFDT
RPA/ACFDT provides access to the correlation energy of a system. It can be understood as an infinite sum of all bubble diagrams in Feynman's diagrammatic language, where excitonic effects are neglected. RPA/ACFDT is used as a post-processing tool on top of a DFT calculation to obtain a more accurate ground-state energy. This category is part of Many-body perturbation theory.
For the theoretical background, see RPA/ACFDT: Correlation energy in the Random Phase Approximation. For a practical step-by-step guide, see ACFDT/RPA calculations.
