We discuss the zero-temperature hydrodynamics equations of bosonic and fermionic superfluids and their connection with generalized Gross-Pitaevskii and Ginzburg-Landau equations through a single superfluid nonlinear Schrodinger equation.
Comments: 4 pages, no figures, prepared for the Special Issue of Laser Physics: Physics of Cold Trapped Atoms; in the second version corrected some typos; in the third version added some useful comments. To be published in Laser Physics (April 2009)
