The existence of a new electronic state in superconductors, materials that can carry an electric current without resistance, has been confirmed experimentally according to research to be published in the
12 November 2004 issue of the journal Science by a team led by Ying Liu, associate professor of physics at Penn State. "We have established direct evidence for the existence of an odd-parity superconductor, which previously had been theorized but never demonstrated in an unambiguous experiment," says Liu. The results culminate six years of experimentation by Liu in collaboration with a former graduate student, Karl Nelson, and a former postdoctoral associate, Zhiqiang Mao at Penn State; and Yoshiteru Maeno, a professor of physics at Kyoto University.From PhysOrg:
