Improving results by improving densities: Density-corrected density functional theory
Eunji Sim, Suhwan Song, Stefan Vuckovic +1
DFT calculations have become widespread in both chemistry and materials, because they usually provide useful accuracy at much lower computational cost than wavefunction-based metho…
Density-corrected DFT explained: Questions and answers
Suhwan Song, Stefan Vuckovic, Eunji Sim +1
HF-DFT, the practice of evaluating approximate density functionals on Hartree-Fock densities, has long been used in testing density functional approximations. Density-corrected DFT…
Explaining and Fixing DFT Failures for Torsional Barriers
Seungsoo Nam, Eunbyol Cho, Kieron Burke +1
Most torsional barriers are predicted to high accuracy (about 1kJ/mol) by standard semilocal functionals, but a small subset has been found to have much larger errors. We create a…
Density sensitivity of empirical functionals
Suhwan Song, Stefan Vuckovic, Eunji Sim +1
Empirical fitting of parameters in approximate density functionals is common. Such fits conflate errors in the self-consistent density with errors in the energy functional, but den…
Measuring density-driven errors using Kohn-Sham inversion
Seungsoo Nam, Suhwan Song, Eunji Sim +1
Kohn-Sham inversion, that is, the finding of the exact Kohn-Sham potential for a given density, is difficult in localized basis sets. We study the precision and reliability of seve…
Density functional analysis: The theory of density-corrected DFT
Stefan Vuckovic, Suhwan Song, John Kozlowski +2
Density-corrected density functional theory (DC-DFT) is enjoying substantial success in improving semilocal DFT calculations in a wide variety of chemical problems. This paper prov…
