Physicists uncover why nanomaterial loses superconductivity

(University of Utah) Physicists have discovered that superconducting nanowires made of MoGe alloy undergo quantum phase transitions from a superconducting to a normal metal state when placed in an increasing magnetic field at low temperatures. The study is the first to uncover the microscopic process by which the material loses its superconductivity. The findings are fully explained by the critical theory proposed by coauthor Adrian Del Maestro.
