The Kohn-Sham gap, the fundamental gap and the optical gap: the physical meaning of occupied and virtual Kohn-Sham orbital energies.
TLDR
A number of consequences of the presence of the exchange-correlation hole potential in the Kohn-Sham potential are elucidated and the spurious nature of HF LUMOs if the orbital energy is positive is stressed.
Existence of minimizers for Kohn-Sham models in quantum chemistry
Comparison of DFT methods for molecular orbital eigenvalue calculations.
TLDR
It is found that TD-DFT with all functionals accurately predicts the HOMO-LUMO gaps and a linear correlation between the calculated HomO eigenvalue and the experimental -IP and calculated Homeric gap and experimental lowest excitation energy enables us to derive a simple correction formula.
Existence of Hartree–Fock excited states for atoms and molecules
For neutral and positively charged atoms and molecules, we prove the existence of infinitely many Hartree–Fock critical points below the first energy threshold (that is, the lowest energy of the same…
The Multiconfiguration Equations for Atoms and Molecules: Charge Quantization and Existence of Solutions
We prove the existence of ground-state solutions for the multiconfiguration self-consistent field equations for atoms and molecules whenever the total nuclear charge Z exceeds N−1, where N is the…

This Perspective outlines the history, basic concepts, and present status of KS-DFT in chemical physics, and offers suggestions for its future development.
Müller’s exchange-correlation energy in density-matrix-functional theory
The increasing interest in the Muller density-matrix-functional theory has led us to a systematic mathematical investigation of its properties. This functional is similar to the Hartree-Fock…
Self-interaction correction to density-functional approximations for many-electron systems
exchange and correlation, are not. We present two related methods for the self-interaction correction (SIC) of any density functional for the energy; correction of the self-consistent one-electron…
Note on Exchange Phenomena in the Thomas Atom
For dealing with atoms involving many electrons the accurate quantum theory, involving a solution of the wave equation in many-dimensional space, is far too complicated to be practicable. One must…
New Optimal Control Problems in Density Functional Theory Motivated by Photovoltaics
TLDR
It is proved that nuclear distributions exist which give rise to optimal HOMO-LUMO excitations, and illustrative numerical simulations for 1D finite nanocrystals are presented.
