Scientists have long been intrigued by strange metals—materials that don’t follow the usual rules of electricity and magnetism. Unlike familiar metals like copper or gold, which conduct electricity in ...

Physicists use the concept of quantum Fisher information to explain poor electrical conductivity in these unusual materials ...

Led by Qimiao Si, the Harry C. and Olga K. Wiess Professor of Physics and Astronomy, the research team turned to quantum Fisher information (QFI), a concept from quantum metrology used to measure ...
