Geometry of Degeneracy in Potential and Density Space

In a previous work [J.Chem.Phys.155, 244111 (2021)], we found counterexamples to the fundamental Hohenberg-Kohn theorem from density-functional theory in finite-lattice systems represented by graphs.Here, we demonstrate that this only occurs at very peculiar Drivetrain and rare densities, those where density sets arising from degenerate ground stat
