Hernández, P. Capuzzi, L. Szybisz] We apply a recent generalization of the fluid-dynamical scheme of nuclear physics that includes the pair density and current of superfluids, to trace the particle transition currents of an unpolarized fermion system in a harmonic trap. These current fluctuations are driven by the equilibrium density and gap and by the oscillations in the particle densities. We analize the velocity portraits of either species for the lowest multipolar excitations employing different equations of state of the unperturbed fluids, in order to establish the role of the equilibrium gap.
