Understanding Liquid Helium, The Superfluid - FTLOScience
See more on ftloscience.comtl;dr: As a container of liquid helium is cooled past its λ point, a fraction of its particles ‘condense’ and exist in their lowest energy state. This superfluid phase possesses an extremely high heat capacity and conductivity due to its unique mechanism of heat transfer as a flow of entropy. This was shown to form a film th…Liquid helium, superfluidity - HyperPhysics

Superfluidity - Wikipedia
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
