Ab initio calculations with the dynamical vertex approximation


  • This article is dedicated to Dieter Vollhardt on the occasion of his 60th birthday.


We propose an approach for the ab initio calculation of materials with strong electronic correlations which is based on all local (fully irreducible) vertex corrections beyond the bare Coulomb interaction. It includes the so-called GW and dynamical mean field theory and important non-local correlations beyond, with a computational effort estimated to be still manageable.
