Fully self-consistent GW calculations for atoms and molecules
Adrian Stan, Nils Erik Dahlen, Robert van Leeuwen
We solve the Dyson equation for atoms and diatomic molecules within the GW approximation, in order to elucidate the effects of self-consistency on the total energies and ionization…

Total energies from variational functionals of the Green function and the renormalized four-point vertex
Robert van Leeuwen, Nils Erik Dahlen, Adrian Stan
We derive variational expressions for the grand potential or action in terms of the many-body Green function which describes the propagation of particles and the renormalized f…
