Electron-Phonon Interactions Cause HTSC
J. C. Phillips
Abstract
What is the microscopic interaction responsible for high temperature superconductivity (HTSC)? Here data on temporal relaxation of Tc and the room temperature conductivity in YBa2Cu3O(6+x) after abrupt alteration by light pulses or pressure changes are analyzed. The analysis proves, independently of microscopic details, that only electron-phonon interactions can cause HTSC in the cuprates; all other interactions are excluded by experiment.
