Electron-Phonon Interactions Cause HTSC

摘要

What is the microscopic interaction responsible for high temperaturesuperconductivity (HTSC)? Here data on temporal relaxation of Tc and the roomtemperature conductivity in YBa2Cu3O(6+x) after abrupt alteration by lightpulses or pressure changes are analyzed. The analysis proves, independently ofmicroscopic details, that only electron-phonon interactions can cause HTSC inthe cuprates; all other interactions are excluded by experiment.
