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…

Parametrizations of local vertex corrections from weak to strong coupling: importance of the Hedin three-leg vertex
Viktor Harkov, Alexander I. Lichtenstein, Friedrich Krien
In the study of correlated systems, approximations based on the dynamical mean-field theory (DMFT) provide a practical way to take local vertex corrections into account, which capt…
