Hohenberg-Kohn Theorem
The Hohenberg-Kohn theorem is a foundational theorem of density functional theory. It establishes that the ground-state electron density uniquely determines the properties of a system and that a universal energy functional exists, providing a theoretical basis for replacing the wavefunction with the electron density.

The Hohenberg-Kohn theorems were proposed by Pierre Hohenberg and Walter Kohn in 1964 and contain two core conclusions: the ground-state electron density uniquely determines the external potential; and there exists a universal energy functional whose minimum corresponds to the ground-state energy.
