An ab initio approach to strongly correlated systems: combining the GW approximation with
dynamical mean field theory
Silke Biermann, LPT-ENS
I will describe a novel approach to electronic structure calculations for
strongly correlated materials. The method is based on a combination of the
GW approximation and dynamical mean field theory. It allows to take into
account long-range Coulomb interactions beyond "LDA+DMFT"-type methods and
includes dynamical screening effects.
We discuss a simplified static approximation to the scheme and its
application to ferromagnetic Nickel.
