https://mazziotti.uchicago.edu/qcdictionary/k_terms/kohn_sham_potential/index.html The Kohn-Sham potential is the effective one-electron potential in the Kohn-Sham equations of density functional theory. It combines the external potential, the Hartree (Coulomb) potential, and the exchange-correlation potential, allowing the many-electron problem to be cast as a set of single-particle equations that yield the exact ground-state density.
