Testing density-functional approximations on a lattice and the applicability of the related Hohenberg-Kohn-like theorem
We present a metric-space approach to quantify the performance of approximations in lattice density-functional theory for interacting many-body systems and to explore the regimes where the Hohenberg-Kohn-type theorem on fermionic lattices is applicable. This theorem demonstrates the existence of one...
