Non-perturbative intertwining between spin and charge correlations: A "smoking gun" single-boson-exchange result
Severino Adler, Friedrich Krien, Patrick Chalupa-Gantner +2
We study the microscopic mechanism controlling the interplay between local charge and local spin fluctuations in correlated electron systems via a thorough investigation of the gen…
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…
