Physicists May Be One Step Closer To Explaining High-Temp Superconductivity

Posted by samzenpus on Sunday March 1, 2015 @06:26AM from the it's-getting-hot-in-here dept.

sciencehabit writes For years some physicists have been hoping to crack the mystery of high-temperature superconductivity—the ability of some complex materials to carry electricity without resistance at temperatures high above absolute zero—by simulating crystals with patterns of laser light and individual atoms. Now, a team has taken—almost—the next-to-last step in such 'optical lattice' simulation by reproducing the pattern of magnetism seen in high-temperature superconductors from which the resistance-free flow of electricity emerges.

138K = -211F
The key threshold is 77K. Above that, and you can cool with liquid nitrogen. A liter of liquid N2 costs less than a liter of milk. A liter of liquid helium costs about a hundred times as much.
