(PhysOrg.com) -- University of Chicago physicists have experimentally demonstrated for the first time that atoms chilled to temperatures near absolute zero may behave like seemingly unrelated natural systems of vastly different scales, offering potential insights into links between the atomic realm and deep questions of cosmology.

BOSTON--The quantum world and the everyday world of human experience are supposed to be two different realms. Quantum effects, as demonstrated in the lab, are usually confined to the tiniest scales.

(PhysOrg.com) -- Many physicists around the world are hard at work trying to figure out new and exciting ways to create ultra-cold objects, the reason being is that if a system could be created that operates at or at least very near absolute zero, superconductors could be devised that might help create quantum computers, which would of course run at speeds that would make the current generation look quaint. Plus, theory suggests new states of matter might be discovered.

(PhysOrg.com) -- Does helium-4 become a "supersolid" near absolute zero? What previous researchers thought might be a supersolid transition is better explained by changes in the solid's resistance to shearing, according to new research by J.
