Learn MoreThe two maps lined up. Where electrons struggled to hop, superconductivity was weak. Where hopping was easy, superconductivity was strong. The relationship between hopping energy and Cooper pair density closely matched a sophisticated numerical prediction from 2021 by Tremblay and colleagues, which argued …
Learn MoreFor many years, the phenomenon of superconductivity could not be satisfactorily explained by the laws of conventional physics. In the early 1950s, however, American physicists John Bardeen, Leon Cooper, and John Schrieffer formulated a theory for superconductivity that earned them the Nobel Prize in Physics in 1972.
