Strictly correlated electrons in density functional theory: A general formulation with applications to spherical densities

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/127726We reformulate the strong-interaction limit of electronic density functional theory in terms of a classical problem with a degenerate minimum. This allows us to clarify many aspects of this limit, and to write a general solution, which is explicitly calculated for spherical densities. We then compare our results with previous approximate solutions and discuss the implications for density functional theory.12 pages, 9 figures. To appear in Phys. Rev.
