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, ...

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 ...

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 ...

Solid Helium It is a material in which quantum phenomena play an important role in determining gross properties. Nonetheless, in a surprising number of cases its behavior resembles that of an ordinary ...
