Description

A new algorithm for the solution of the Hartree-Fock equations is presented, which avoids matrix diagonalizations. The method is built around the variance of the Hartree-Fock hamiltonian, computed with respect to vectors arising from the Hartree-Fock transformation, and tries to make it vanish. The present approach is applied to the Lipkin model and to a simple numerical example. (author)
