Hedin Equations, GW, GW+DMFT, and All That
K. Held, C. Taranto, G. Rohringer +1
Historically, the GW approach was put forward by Hedin as the simplest approximation to the so-called Hedin equations. In Section 2, we will derive these Hedin equations from a Fey…

Ab initio calculations with the dynamical vertex approximation
A. Toschi, G. Rohringer, A. A. Katanin +1
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…

Critical properties of the half-filled Hubbard model in three dimensions
G. Rohringer, A. Toschi, A. A. Katanin +1
By means of the dynamical vertex approximation (DA) we include spatial correlations on all length scales beyond the dynamical mean field theory (DMFT) for the half-filled Hubbar…
