Towards chemical accuracy: Fermi-Löwdin orbital self-interaction corrected density functional theory

POSTER

Abstract

In this contribution the authors give a brief insight into the Fermi-Löwdin orbital self-interaction correction (FLO-SIC) method. FLO-SIC restores the correct 1/r behavior which will be shown based on various dissociation curves for diatomic molecules. Further, the binding energies are significantly improved compared to standard semilocal exchange-correlation functionals. In addition to the improved energetics, the Fermi-Löwdin orbitals allow a straightforward analysis of chemical bonding.
We present a simple, ab-initio approach to investigate bond-order, aromaticity and (hyper-)valency of molecules and clusters.
