FLO-SIC DFT applied to pseudopotentials — •Simon Liebing, Sebastian Schwalbe, Torsten Hahn, and Jens Kortus — TU Bergakademie Freiberg, Institute for Theoretical Physics, Germany

A method bases on Fermi-Löwdin orbitals to correct the self-interaction error within DFT (FLO-SIC) was developed by Pederson and co-workers. [1,2,3] The authors show how the FLO-SIC method can be used within the pseudopotential methodology. The calculation speedup and accuracy in comparison with all-electron calculations are discussed in detail. The FLO-SIC pseudopotential scheme leads to a similar improvement of the ionization potentials, eigenvalues and bond energies compared to the all-electron variant.
