Density-functional expansion methods: Evaluation of LDA, GGA, and meta-GGA functionals and different integral approximations

We extend the Kohn–Sham potential energy expansion (VE) to include variations of the kinetic energy density and use the VE formulation with a 6-31G* basis to perform a “Jacob’s ladder” comparison of small molecule properties using density functionals classified as being either LDA, GGA, or meta-GGA....
