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-quality, ...

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

In the Friday 3 September 2004 issue of Science Express, two physicists from Penn State University will announce new experimental evidence for the existence of a new phase of matter, a "supersolid" ...

In 2004 researchers reported the first clear evidence for superfluidity in solid helium-4. However, Matthew Chalmers describes recent experimental and theoretical work that has brought the very ...

This is a preview. Log in through your library . Abstract Supersolidity, the appearance of zero-viscosity flow in solids, was first indicated in helium-4 torsional oscillator (TO) experiments. In this ...

Two physicists from Penn State University will announce new experimental evidence for the existence of a new phase of matter, a "supersolid" form of helium-4 with the extraordinary ...

Evidence is mounting for the existence of a strange new state of matter called a "supersolid", in which a small fraction of ultracold helium decouples from the rest of the solid and flows effortlessly ...

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 ingenious ...

John Reppy has come out of retirement to question the high-profile discovery of a new kind of quantum matter. The fourth time he is asked what the dental floss is for, John Reppy seems to hear. He ...
