报告内容:
The interactions between charge carriers and lattice vibrations in solids, also known as electron-phonon interactions, controls a range of physical processes 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. In this talk, I will present our recently developed methods to compute electron-phonon interactions from first principles, and show how these advances enable accurate calculations of charge transport and ultrafast dynamics in complex materials. In addition, I will discuss our efforts to develop an open source code, Perturbo, that makes these novel computational tools available to the community.
