Approaching Coupled Cluster Accuracy with Positive Semidefinite Vertex Corrected Self-Energies

Yaroslav Pavlyukh, Fabien Bruneval, Arno Förster

Hedin's formalism of functional derivatives is the best-known method for systematically constructing correlated electronic theories, largely due to the success of its lowest-order…

reduced density matrix from iterated linearized Dyson equation

Fabien Bruneval, Erik Verzijl, Arno Förster +1

Iterating the Dyson equation with the static part of the self-energy leads to a concise and possibly improved expression of the one-body reduced density matrix from any self-energy…
