Site-occupation--Green's function embedding theory: A density-functional approach to dynamical impurity solvers
Laurent Mazouin, Matthieu Saubanère, Emmanuel Fromager
A reformulation of site-occupation embedding theory (SOET) in terms of Green's functions is presented. Referred to as site-occupation--Green's function embedding theory (SOGET), th…

Exploring weight-dependent density-functional approximations for ensembles in the Hubbard dimer
Killian Deur, Laurent Mazouin, Bruno Senjean +1
Gross-Oliveira-Kohn density-functional theory (GOK-DFT) is an extension of DFT to excited states where the basic variable is the ensemble density, i.e. the weighted sum of ground-…
