WebStarting with the Hartree–Fock wavefunction as the ground determinant, one takes a linear combination of the ground and excited determinants as the correlated wavefunction and optimizes the weighting factors according to the Variational Principle. When taking all possible excited determinants, one speaks of Full-CI. WebAug 16, 2024 · In computational physics and chemistry, the Hartree–Fock ( HF) method is a method of approximation for the determination of the wave function and the energy of a quantum many-body system in a stationary state . The Hartree–Fock method often assumes that the exact, N -body wave function of the system can be approximated by a …
