- Superfluidity is a characteristic property of a fluid with zero viscosity which therefore flows without any loss of kinetic energy1. It occurs in two isotopes of helium (helium-3 and helium-4) when they are liquefied by cooling to cryogenic temperatures1. The theory of superfluidity describes the property of a macroscopic system in a state that does not have the full symmetry of the underlying microscopic dynamics2. The order parameter measures the existence of Bose condensed particles (Cooper pairs) and is given by the probability amplitude of such particles2. The theory is based on coupled hydrodynamic equations for the superfluid and normal fluid components3.

Landau's two-fluid description is only valid when collisions among the thermal excitations making up the normal fluid are strong enough to produce local hydrodynamic equilibrium. These two-fluid equations were originally developed for liquid.www.cambridge.org/core/books/bosecondensed-g… - People also ask

Superfluidity is the characteristic property of a fluid with zero viscosity which therefore flows without any loss of kinetic energy. When stirred, a superfluid forms vortices that continue to rotate indefinitely. Superfluidity occurs in two isotopes of helium (helium-3 and helium-4) when they are liquefied by cooling to cryogenic temperatures. It is also a property of various other exotic states of matter
