. We analyze the inverse problem of Density Functional Theory using a regularized variational method. First, we show that given k and a target density ρ , there exist potentials having k th excited mixed states which densities are arbitrarily close to ρ . The state can be chosen pure in dimension d = 1 and without interactions, and we provide numerical and theoretical evidence consistently leading us to conjecture that the same pure representability result holds for d = 2 , but that the set of…

Complete solution to the inverse Kohn-Sham problem: From the density to the energy
A complete solution to the inverse problem of Kohn-Sham (KS) density functional theory is proposed. Our method consists of two steps. First, the effective KS potential is determined from the ground…
DFTK: A Julian approach for simulating electrons in solids
Density-functional theory (DFT) is a widespread method for simulating the quantum-chemical behaviour of electrons in matter. It provides a first-principles description of many optical, mechanical and…
Nuclear energy density functionals from empirical ground-state densities
A model is developed, based on the density functional perturbation theory and the inverse KohnSham method, that can be used to improve relativistic nuclear energy density functionals towards an exact…
Some Properties of the Potential-to-Ground State Map in Quantum Mechanics
We analyze the map from potentials to the ground state in static many-body quantum mechanics. We first prove that the space of binding potentials is path-connected. Then we show that the map is…

Universal nature of different methods of obtaining the exact Kohn–Sham exchange-correlation potential for a given density
An interesting fundamental problem in density-functional theory of electronic structure of matter is to construct the exact Kohn-Sham (KS) potential for a given density. The exact potential can then…
Density-inversion method for the Kohn-Sham potential: Role of the screening density.
TLDR
This work presents a method to invert a given density and find the Kohn-Sham potential in Density Functional Theory that shares the density and demonstrates the applicability of the method by inverting both local and non-local densities.
Lack of Hohenberg-Kohn theorem for excited states.
For a given excited state there exist densities that arise from more than one external potential. This is due to a qualitatively different energy-density relationship from that of the ground state…
