superconductivity

For the first time, physicists have experimentally validated a 1959 conjecture that places limits on how small superconductors can be. Understanding superconductivity (or the lack thereof) on the nanoscale is expected to be important for designing future quantum computers, among other applications. In 1959, physicist P.W. Anderson conjectured that superconductivity can exist only in objects … Continue reading How small can superconductors be? →

RICE University physicists Qimiao Si and Rong Yu have a theoretical explanation for a state in which a material simultaneously exhibits the conflicting characteristics of a metallic conductor and an insulator.
