Towards chemical accuracy of FLO-SIC — •Sebastian Schwalbe1, Torsten Hahn1, Simon Liebing1, Kai Trepte2, and Jens Kortus11TU Bergakademie Freiberg, Institute for Theoretical Physics, Germany — 2Central Michigan University, Department of Physics, USA

Fermi-Löwdin orbital self-interaction correction (FLO-SIC) [1,2,3] is applied to atoms and molecules as defined in the standard G2-1 test set. Within this systematic study calculated ionization potentials and binding energies are compared with experimental values. It will be shown that the FLO-SIC method provides significant improvements towards chemical accuracy by using the framework with the LSDA functional, but noteworthy worse performance in combination with the PBE-GGA or other GGA functionals.
