Conditional probability density functional theory

Conditional probability density functional theory (CP-DFT) determines the ground-state energy of a many-electron system by finding conditional from parallelizable series Kohn-Sham DFT calculations. By directly calculating densities, authors bypass need for an approximate exchange-correlation (XC) functional. CP-DFT is formally exact, but potentials are used in practice. We explore suitable approximation that satisfies many presented exact constraints and even properly dissociates neutral hydrogen chains.
