The Hartree Approximation Next:The Hartree-Fock ApproximationUp:One-Electron MethodsPrevious:One-Electron Methods The Hartree Approximation This approximation starts from the one-electron equations ofEq(). is chosen to try to model theinteraction terms in this equation. The ions contribute a potential

What are Hartree equations?

leads to a set of single particle equations, which are the same as substituting Eq.() inEq.( These equations are known as the Hartreeequations. Next:The Hartree-Fock ApproximationUp:One-Electron MethodsPrevious:One-Electron Methods

Is Hartree a determinant?

It is inherently mean-field (assumes the particles are independent) and is the unsymmetrized version of the Slater determinant ansatz in the Hartree–Fock method. Although it has the advantage of simplicity, the Hartree product is not satisfactory for fermions, such as electrons, because the resulting wave function is not antisymmetric.

What is Hartree-Fock method?

1. Introduction The Hartree-Fock method is a basic method for approximating the solution of many-body electron problems in atoms, molecules, and solids. With modifications, it is also extensively used for protons and neutrons in nuclear physics, and in other applications.
