What does WHH mean in UNCLASSIFIED
The WHH theorem states that the ground state energy of a many-electron system is a unique functional of the electron density. This means that all the properties of the ground state of the system, such as the energy, electron density, and wavefunction, can be determined from the electron density alone.

Essential Questions and Answers on Werthamer Helfand and Hohenberg in "MISCELLANEOUS»UNFILED"
What is the Werthamer Helfand and Hohenberg (WHH) theorem?
What are the implications of the WHH theorem?
The WHH theorem has several important implications. First, it shows that the Hohenberg-Kohn theorem is exact, meaning that the electron density is a sufficient variable to describe the ground state of a many-electron system. Second, it provides a theoretical justification for the use of density functional theory (DFT) to calculate the properties of many-electron systems. Third, it shows that the electron density is a fundamental property of a many-electron system.
How can the WHH theorem be used in practice?
The WHH theorem can be used in practice to calculate the ground state energy and other properties of many-electron systems using DFT. DFT is a computationally efficient method that can be used to study a wide range of systems, from small molecules to large solids. DFT is used in a variety of fields, including chemistry, physics, and materials science.
