New Wrinkle in the Mystery of High-Tc Superconductors
March 16, 2006
In the twenty years since the discovery of high-temperature (Tc) superconductors, scientists have been trying to understand the mechanism by which electrons pair up and move coherently to carry electrical current with no resistance. "We are still at the beginning," says Tonica Valla, a physicist at Brookhaven, who will give a talk on his group's latest results at the American Physical Society meeting in Baltimore, Maryland on Thursday, March 16, 2006.
