Superconductors are materials that can conduct electricity with zero resistance when they are cooled below a certain critical temperature. They have applications in several fields, including magnetic ...

In 2020, researchers reported that they had created a room-temperature superconductor. That paper has now been retracted. Editor’s Note: On September 26, 2022, the journal Nature retracted the paper ...

The pursuit of room-temperature superconductivity has long been a holy grail in the field of condensed matter physics because it could revolutionize all electricity based technologies and in ...
