Alternative explanation for exotic state of matter posited in new Science paper The long-held, but unproven idea that helium-4 enters into an exotic phase of matter dubbed a "supersolid" when cooled to extremely low temperatures has been challenged in a new paper published recently in Science. Los Alamos National Laboratory researchers Alexander Balatsky and Matthias Graf joined Cornell University physicist J.C. S©amus Davis and others in describing an alternative explanation for...

In a four-decade, Holy Grail-like quest to fully understand what it means to be in a "supersolid" state, physicists have found that supersolid isn't always super solid. In other words, this exotic state of frozen helium appears to have liquid-like properties, says a new paper published in the journal Science (May 13, 2011). Why is this important? Understanding supersolid helium brings us closer to understanding its close cousins superconductivity and superfluidity. Physicists had long thought...

If physicists lived in Flatland"”the fictional two-dimensional world invented by Edwin Abbott in his 1884 novel"”some of their quantum physics experiments would turn out differently (not just thinner) than those in our world. The distinction has taken another step from speculative fiction to real-world puzzle with a paper* from the Joint Quantum Institute (JQI) reporting on a Flatland arrangement of ultracold gas atoms. The new results, which don't quite jibe with earlier Flatland...

Physicists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland have proposed a recipe for turning ultracold "boson" atoms"”the ingredients of Bose-Einstein condensates"”into a "supersolid," an exotic state of matter that behaves simultaneously as a solid and a friction-free superfluid. While scientists have found evidence for supersolids in complex liquid helium mixtures, a supersolid formed from such...
