SYIS: Symposium Progress and Challenges in Modelling Electron-Phonon Interaction in Solids

SYIS 1: Progress and Challenges in Modelling Electron-Phonon Interaction in Solids

Tuesday, March 18, 2025, 09:30–12:15, H1

Electron-phonon interaction is crucial to predict and explain material behaviour under a variety of equilibrium and non-equilibrium conditions. Though recent developments in theoretical and computational methods have significantly advanced our capability, significant challenges still remain to be addressed. An accurate description of electron-phonon interactions in complex materials, including e.g., disordered perovskites, correlated oxides, superconductors, interfaces, and heterostructures, is often beyond the capability of existing methodologies. This symposium will bridge different communities working on electron-phonon interactions in solids and pinpoint common problems and open challenges in the field.
