Hohenberg–kohn theorems
Nettet23. jan. 2024 · Hohenberg-Kohn (HK) theorem is a cornerstone of modern electronic structure calculations. For interacting electrons, given that the internal part of the Hamiltonian ($\\hat H_{int}$), containing the kinetic energy and Couloumb interaction of electrons, has a fixed form, the theorem states that when the electrons are subject to … NettetThe Hohenberg-Kohn theorem is extended to the case that the external potential is …
