1. A quantum fluid pipes up

Subjects
Liquid helium -- Research, Quantum theory -- Research, Helium -- Research, Science and technology
Abstract

Helium never ceases to amaze. Physicists have now heard a quantum-mechanical whistle emanating from two reservoirs of liquid helium-4 that were separated by a perforated membrane. According to theory, when [...]

2. Microdrops of superfluid

Author

Peterson, Ivars

Subjects
Liquid helium -- Research, Superfluidity -- Research, Science and technology, Research
Abstract

Liquid helium cooled to temperatures lower than 2.12 kelvins can become a superfluid, flowing without friction. Now, researchers have shown experimentally that superfluidity can occur in a cluster consisting of [...]

3. Confining superfluid helium to a new state

Author

Peterson, Ivars

Subjects
Liquid helium -- Research, Superfluidity -- Research, Science and technology, Research
Abstract

Superfluid helium-3 represents one of the more exotic forms of matter created in the laboratory. At temperatures below 2.5 millikelvins, this liquid can flow without friction (SN: 10/19/96, p. 247). [...]

4. Swirls of superfluid flow

Author

Peterson, Ivars

Subjects
Thin films -- Research, Liquid helium -- Research, Dielectric films -- Research, Superfluidity -- Research, Science and technology, Research
Abstract

Swirls of super fluid flow Chilling liquid helium to temperatures below 2.172 kelvins has a curious effect. The helium changes into a superfluid, a state in which the liquid flows [...]

Author

Peterson, Ivars

Subjects
Helium at low temperatures -- Research, Liquid helium -- Research, Superfluidity -- Research, Helium -- Isotopes, Science and technology, Research
Abstract

Quantum swirls in superfluid helium At sufficiently low temperatures, liquid helium becomes a superfluid, flowing without friction. This curious property is one of the more startling consequences of the role [...]
