Michele Casula: Satellites from dynamic screening in an extended DMFT framework: applications to SrVO3 and BaFe2As2 In this talk I present new methods to include the dynamically screened U in an extended DMFT ab-initio framework. I show how the frequency dependence of U comes naturally out from downfolding of the electronic structure, and I introduce the new features the frequency dependence brings in, as the plasmon satellites together with a renormalization of the low-energy properties in the spectra of strongly correlated systems. The cases of SrVO3 and BaFe2As2 are analyzed.
Thomas Ayral: Spectral properties of the extended Hubbard model: insights into screening and non-local correlations from fully self-consistent combination of GW and dynamical mean field theory
