Quotes About Superfluid

Superfluid helium is a realization of the hypothetical quantum liquid that we imagined when performing the thought experiment with the buckets on the staircase. Its behavior is almost surreal.

3He becomes a superfluid below 10?3 K, when its fermionic atoms pair up into bosons and condense. Similar condensation of paired fermions also occurs in neutron stars at about 106 K.
