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 ...

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 ...

Fritz London Memorial Prize recognizes pathbreaking work in low-temperature physics AMHERST, Mass. — Robert B. Hallock, distinguished professor emeritus of physics at the University of Massachusetts ...

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 ...

Two Canadian researchers discovered a new form of matter yesterday. They call it “supersolid helium,” and it’s stiffer than any solid matter ever seen on Earth. Above you can see an image of solid ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. When you purchase through ...

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...
