Standard calculations of electron-phonon coupling usually assume that phonons have infinite lifetimes, however phonons can exhibit finite lifetimes on account of anharmonic phonon-phonon interactions. On this work, we derive an expression for the electron-phonon coupling scattering charges together with the consequences of anharmonic three-phonon interactions, which result in phonon dephasing and finite phonon lifetimes. We additionally describe a first-principles implementation of this anharmonic electron-phonon coupling which will be seamlessly built-in inside current workflows for the analysis of electron-phonon and phonon-phonon coupling interactions. Lastly, we current calculations of electron-phonon scattering charges together with phonon dephasing in a variety of supplies, and talk about the totally different microscopic mechanisms by which anharmonic phonons affect electron-phonon coupling. This research establishes the significance of finite phonon lifetimes within the analysis of electron-phonon coupling, and supplies a platform to discover these results in a variety of supplies and phenomena.<br \/>\n<br \/><br \/>\n<br \/><a href=\"https:\/\/arxiv.org\/abs\/2608.09039\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>arXiv:2608.09039v1 Announce Kind: cross Summary: Electron-phonon coupling has been a central subject in condensed matter physics for many years, and firstprinciples strategies have demonstrated outstanding success in quantitatively capturing its function in all kinds of bodily phenomena and supplies.
