Hartree-Fock Energy: Two Electrons Case

This lecture delves into the Hartree-Fock energy expression, starting with the detailed derivation and application to a 2-electron system. The instructor explains the total energy of the electronic Hamiltonian using Slater determinant wavefunctions and explores the exchange and Coulomb integrals. The lecture also covers the self-interaction energy, Hund's rule, and the comparison between Hartree and antisymmetrized products.
