superfluidity
/ ˌsuːpəfluːˈɪdɪtɪ /
noun
- physics the state of being or property of becoming a superfluid
Example Sentences
Research the Will lab is excited to pursue with their molecular BECs includes exploring a number of different quantum phenomena, including new types of superfluidity, a state of matter that flows without experiencing any friction.
"We would like to use the BECs in a 2D system. When you go from three dimensions to two, you can always expect new physics to emerge," he said. 2D materials are a major area of research at Columbia; having a model system made of molecular BECs could help Will and his condensed matter colleagues explore quantum phenomena including superconductivity, superfluidity, and more.
In 1938, the physicist László Tisza proposed a two-fluid model for superfluidity -- that a superfluid is actually a mixture of some normal, viscous fluid and a friction-free superfluid.
"Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection of the density ripples that go along with it," Zwierlein says.
"For the first time, we can take pictures of this substance as we cool it through the critical temperature of superfluidity, and directly see how it transitions from being a normal fluid, where heat equilibrates boringly, to a superfluid where heat sloshes back and forth," Zwierlein says.
