Stabilization of solution of the Hartree-Fock equations☆
Robert D. Cowan,Joseph B. Mann +1 more
TL;DR: In this paper, a simple method is described for eliminating certain instabilities and other difficulties in the solution of the Hartree-Fock (HF) equations, which consists of subtracting, from both the homogeneous and inhomogeneous portions of the differential equation, terms which exactly compensate each other in the self-consistent limit.
