# Hohenberg–Kohn Theorems for Interactions, Spin and Temperature

@article{Garrigue2019HohenbergKohnTF, title={Hohenberg–Kohn Theorems for Interactions, Spin and Temperature}, author={Louis Garrigue}, journal={Journal of Statistical Physics}, year={2019} }

We prove Hohenberg-Kohn theorems for several models of quantum mechanics. First, we show that for possibly degenerate systems of several types of particles, the pair correlation functions of any ground state contain the information of the interactions and of the external potentials. Then, in the presence of the Zeeman interaction, a strong constraint on external fields is derived for systems having the same ground state densities and magnetizations. Next, we prove that the density and the…

It is proved that Diener’s formulation is unfortunately not capable of reproducing the correct ground-state energy and, furthermore, that the suggested construction of a Hohenberg–Kohn map contains an irreparable mistake.
