Helium-3 to the rescue. To make the case for super-solidity, researchers turned to a form of helium that does not turn into a super-solid: helium-3.

Solid helium can behave like a superfluid. Solid helium can behave like a superfluid. Skip to main content. Scientific American. January 17, 2005. 3 min read. A Glimpse of Supersolid.

High-quality, single-crystal, ultra-cold solid helium exhibits supersolid behavior, suggesting that this frictionless solid flow is not a consequence of defects and grain boundaries in poor ...

Solid helium forms in the channel when the cell is cooled below -270 Celsius, or 3 degrees above absolute zero, under a pressure that exceeds 26 times the normal atmospheric pressure.

Despatches from Holland related that a Professor Keesom had solidified that rare and undemonstrative gas, helium, by a process not too costly or laborious to be adopted industrially. By some ...

The team placed solid helium-4 in an array of capillaries and searched for direct evidence of supersolidity by creating a pressure difference in the sample and seeing whether any mass flowed as a ...

The porous glass was inside a leak-tight capsule, and the helium gas became a solid when the pressure inside the capsule reached 40 times the normal atmospheric pressure.

Frozen helium prepared in a laboratory has apparently transformed into a superfluid solid, or supersolid—a never-before-seen phase of matter that theorists predicted more than 30 years ago.

A would-be explanation for the quantum phase of matter known as a supersolid has been ruled out by a new experiment. Physicists in the US have found evidence for supersolidity in single crystals of ...

Solid helium represents a unique quantum solid whose low temperature properties challenge conventional understanding of condensed matter. Its remarkable behaviour, including supersolidity and ...
