Long-term memory magnetic correlations in the Hubbard model: A dynamical mean-field theory analysis
Clemens Watzenböck, Martina Fellinger, Karsten Held +1
We investigate the onset of a not-decaying asymptotic behavior of temporal magnetic correlations in the Hubbard model in infinite dimensions. This long-term memory feature of dynam…
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:…
Explaining the pseudogap through damping and antidamping on the Fermi surface by imaginary spin scattering
Friedrich Krien, Paul Worm, Patrick Chalupa +2
The mechanism of the pseudogap observed in hole-doped cuprates remains one of the central puzzles in condensed matter physics. We analyze this phenomenon via a Feynman-diagrammatic…
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…
