Electron-Phonon Interaction in Metals: Limits and Implications

Explore the limits of electron-phonon interaction in metals through this comprehensive lecture by Boris Altshuler from PCS Institute for Basic Science. Delve into the Migdal-Eliashberg approach to analyze the electron-phonon coupling, discovering the critical value beyond which instability occurs. Investigate the implications of this upper bound on superconducting transition temperatures and its potential connection to metal-insulator transitions. Compare theoretical bounds with experimental data to gain insights into the fundamental physics of electron-phonon interactions in metallic systems. This 1 hour and 29 minutes talk provides a deep dive into the intricacies of condensed matter physics and superconductivity.
