A family of intracules, a conjecture and the electron correlation problem

Gill, Peter; Crittenden, Deborah; O'Neill, Darragh P; Besley, Nicholas


We present a radical approach to the calculation of electron correlation energies. Unlike conventional methods based on Hartree-Fock or density functional theory, it is based on the two-electron phase-space information in the Omega intracule, a three-dimensional function derived from the Wigner distribution. Our formula for the correlation energy is isomorphic to the Hartree-Fock energy expression but requires a new type of four-index integral. Preliminary results, obtained using a model that...[Show more]
