Researchers at Japan's Tohoku University are making a bold claim: an entirely new state of matter. The team, led by Kosmas Prassides, says they've created what's called a Jahn-Teller metal by inserting rubidium, a strange alkali metal element, into buckyballs, a pure carbon structure which has a spherical shape from a series of interlocking polygons (think of the Epcot Center, but in microscopic size.) The researchers created a complex crystalline structure that seemed to conduct, insulate, and magnetize while acting as a metal. It goes far beyond what ordinary matter can do. So what's the big deal? Applying pressure to the compound when it's in the conductor/insulator phase turns it into the weird state of matter, and also makes it superconductive at (relatively) high temperatures. Most superconductors that we know of need to be barely above absolute zero. Understanding and then mastering high-temperature superconductors, which this weird state of matter could help researchers to do, could make all sorts of new things possible in computing, transportation, infrastructure ... sort of everything. Discoveries of superinsulators in 2008 sort of hinted that this state of matter was possible, but confirmation would be a game changer for materials science.
