Perturbation expansion for a Fermi superfluid .2. Several equilibrium properties

The formalism of the preceding paper is applied to a system of uniform flow. Explicit expressions are obtained for the specific heat: C-V, the superfluid-density tensor: rho, and the spin susceptibility of the singlet pairing: chi. It is the quasiparticle excitation near the excitation threshold that is responsible for these quantities. The three expressions for upsilon = 0 reduce to the normal-state results of Luttinger; the Leggett expressions of rho and chi are reproduced by neglecting the feedback effects.
