Physicists uncover why nanomaterial loses superconductivity: All details predicted by critical theory were confirmed on real objects in a lab

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.
