Superfluid helium-4 is the best studies example of superfluidity. Helium-4 transitions from a liquid into a superfluid just a few degrees below its boiling point of -452 °F (-269 °C or 4 K). Superfluid helium-4 looks like a normal clear liquid. However, because it has no viscosity, once it starts flowing, it … See more

At present, there aren’t many practical applications of superfluids. However, superfluid helium-4 is a coolant for high-field magnets. Both helium-3 and helium-4 find use in exotic particle detectors. Indirectly, researching superfluidity aids in understanding how … See more
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
