摘要
The Hohenberg-Kohn theorem plays a fundamental role in density functional theory, which has become the most popular and powerful computational approach to study the electronic structure of matter.In this article, we study the Hohenberg-Kohn theorem for a class of external potentials based on a unique continuation principle.
