Degenerate ground states and nonunique potentials: Breakdown and restoration of density functionals
(American Physical Society, 2007)The Hohenberg-Kohn (HK) theorem is one of the most fundamental theorems of quantum mechanics, and constitutes the basis for the very successful density-functional approach to inhomogeneous interacting many-particle systems. ...
