Query: Effective interactions in the stripe state of the two-dimensional
  Hubbard model   We investigate the structure of the pairing potential in the stripe phase of
the two-dimensional Hubbard model. Based on the random phase approximation we
discuss in detail the interactions in the charge- and spin channel and compare
our calculations with related considerations in commensurate antiferromagnets.
Our main finding is that due to the incommensurate charge-density wave
formation the exchange of collective modes in the charge channel is
significantly enhanced with respect to the spin bag approach whereas due to the
inhomogeneous charge distribution the coupling to transverse spin fluctuations
tends to be suppressed.
