Parquet-like equations for the Hedin three-leg vertex
Friedrich Krien, Angelo Valli
Taking the competition and the mutual screening of various bosonic fluctuations in correlated electron systems into account requires an unbiased approach to the many-body problem.…

Single-boson exchange decomposition of the vertex function
Friedrich Krien, Angelo Valli, Massimo Capone
We present a decomposition of the two-particle vertex function of the single-band Anderson impurity model which imparts a physical interpretation of the vertex in terms of the exch…

Efficient evaluation of the polarization function in dynamical mean-field theory
Friedrich Krien
The dynamical susceptibility of strongly correlated electronic systems can be calculated within the framework of the dynamical mean-field theory (DMFT). The required measurement of…
