Query: Interplay between magnetic and superconducting fluctuations in the doped
  2d Hubbard model   We study the Hubbard model on a square lattice, using the dynamical vertex
approximation and the parquet approximation. These methods allow us to describe
the mutual interference of spin-fluctuations in the particle-hole channel and
superconducting fluctuations in the cooperon channel in an unbiased way. For
small dopings we find predominant commensurable antiferromagnetic spin- and
d-wave superconducting fluctuations; for larger doping incommensurate
antiferromagnetic spin fluctuations are concomitant to triplet s-wave
superconducting fluctuations.
