How Was Superfluidity Discovered?

In 1927 Willem Keesom and Mieczyslaw Wolfke concluded that that liquid helium undergoes a phase transition at about 2.2 K. ... The truly remarkable result, that helium II is a superfluid, was first discovered in 1937 and published in January 1938, by Pyotr Kapitsa in Moscow, and independently by John F.

Who invented superfluidity?

Superfluidity (in the form of frictionless flow through narrow capillaries) was discovered in 4He below 2.17 K (− 290.98 °C, or − 455.76 °F) in 1938, simultaneously by Soviet physicist Pyotr Leonidovich Kapitsa and by Canadian physicists John F. Allen and A.D. Misener.

How is superfluidity made?

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 theorized to exist in astrophysics, high-energy physics, and theories of quantum gravity.
