Fulfillment of sum rules and Ward identities in the multiloop functional renormalization group solution of the Anderson impurity model
Patrick Chalupa-Gantner, Fabian B. Kugler, Cornelia Hille +3
We investigate several fundamental characteristics of the multiloop functional renormalization group (mfRG) flow by hands of its application to a prototypical many-electron system:…

Single boson exchange representation of the functional renormalization group for strongly interacting many-electron systems
Pietro M. Bonetti, Alessandro Toschi, Cornelia Hille +2
We present a reformulation of the functional renormalization group (fRG) for many-electron systems, which relies on the recently introduced single boson exchange (SBE) representati…
