Hohenberg & Kohn: electron density as a foundation

What changed

Established a variational foundation for describing an interacting electronic ground state through its density.

Scientific scope

Established a variational foundation for describing an interacting electronic ground state through its density. Scope limitation: The theorem’s assumptions matter. It does not supply an exact practical exchange-correlation functional for every material.

Evidence

Assessment uses the catalogue-linked source evidence for the stated contribution. The theorem’s assumptions matter. It does not supply an exact practical exchange-correlation functional for every material.
