Superfluid current in ${}_{}{}^3{}_{}{}^{}\mathit{A}$ at T=0. II

We show that, except for the correction in the longitudinal superfluid density ${\rho }_{s?}$ =ρ[1-(3/2)(ħ$v_F$/δ) ‖(l^⋅∇)l^‖], all the nonanalytic contributions to the supercurrent which have been studied previously vanish. It is shown that, if one does not use a gauge transformation, one has to go beyond the linear approximation for the spatial variations of the gap in order to treat consistently the superfluid velocity.
