Abstract：

　　Interactions between charge carriers and lattice vibrations control a range of physical processes in solids, including charge transport, excited carrier dynamics, ultrafast spectroscopy, and spin decoherence. Conventional electron-phonon calculations rely on empirical treatments that lack predictive power and quantitative accuracy. I will present recently developed methods to compute electron-phonon interactions from first principles and show how these advances enable quantitative calculations of charge transport in complex oxides. Additionally, I will discuss our efforts to develop an open source code, Perturbo, that makes these novel computational tools available to the community.
