  We discuss the evolution from BCS to Bose superfluidity for ultracold
fermions in two-dimensions and in the presence of simultaneous spin-orbit and
Zeeman fields. We analyze several thermodynamic properties to characterize
different superfluid phases including pressure, compressibility, induced
polarization, and spin susceptibility. Furthermore, we compute the momentum
distribution and construct topological invariants for each of the superfluid
phases.
