Query: Enhancement of the d-wave pairing correlations by charge and spin
  ordering in the spin-one-half Falicov-Kimball model with Hund and
  Hubbard~coupling   Projector Quantum-Monte-Carlo Method is used to examine effects of the
spin-independent $U_{fd}$ as well as spin-dependent $J_z$ Coulomb interaction
between the localized $f$ and itinerant $d$ electrons on the stability of
various types of charge/spin ordering and superconducting correlations in the
spin-one-half Falicov-Kimball model with Hund and Hubbard coupling. The model
is studied for a wide range of $f$ and $d$-electron concentrations and it is
found that the interband interactions $U_{fd}$ and $J_z$ stabilize three basic
types of charge/spin ordering, and namely, (i) the axial striped phases, (ii)
the regular $n$-molecular phases and (iii) the phase separated states. It is
shown that the d-wave pairing correlations are enhanced within the axial
striped and phase separated states, but not in the regular phases. Moreover, it
was found that the antiferromagnetic spin arrangement within the chains further
enhances the d-wave paring correlations, while the ferromagnetic one has a
fully opposite effect.
