Understanding the origin of superconductivity in high-temperature copper oxide superconductors

Superconductors are materials that can conduct electricity with zero resistance when cooled to a certain temperature, called the critical temperature. They have applications in many fields, including power grids, maglev trains, and medical imaging. High-temperature superconductors, which have critical temperatures higher than normal superconductors have significant potential for advancing these technologies. However, the mechanisms behind their superconductivity remain unclear.
