Particle currents in a fluid-dynamical description of two trapped fermion species

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...
