Pairing boost from enhanced spin-fermion coupling in the pseudogap regime
Yang Yu, Sergei Iskakov, Emanuel Gull +2
We perform a fluctuation analysis of the pairing interaction in the hole-doped Hubbard model within the dynamical cluster approximation. Our analysis reveals that spin-fluctuation-…

Screening and effective RPA-like charge susceptibility in the extended Hubbard model
Aiman Al-Eryani, Sarah Heinzelmann, Kilian Fraboulet +2
We generalize the recently introduced single-boson exchange formalism to nonlocal interactions. In the functional renormalization group application to the extended Hubbard model in…
