Query: Pairing in Asymmetrical Fermi Systems with Intra- and Inter-Species
  Correlations   We consider inter- and intra-species pairing interactions in an asymmetrical
Fermi system. Using equation of motion method, we obtain coupled mean-field
equations for superfluid gap functions and population densities. We construct a
phase diagram across BCS-BEC regimes. Due to intra-species correlations, the
BCS singlet superfluid state can sustain finite polarizations, $P$. For larger
$P$, we find phase separations in BCS and BEC regimes. A superfluid phase
exists for all $P$ deep in BEC regime. Our results may apply to pairing in
ultracold fermions, nuclear and quark matter physics.
