Superfluid is a fluid with an extremely low viscosity and high thermal conductivity. The current description of superfluidity, first proposed by Tisza [1] soon after the discovery of Helium-4 superfluidity, is based on the assumption that two different fluids coexist. One is the superfluid, which corresponds to the condensed gas. The other is the normal fluid, which in our current view is made of quasi-particle excitations, or phonons.
