WebMay 10, 2024 · We present a new first-principles linear-response theory of changes due to perturbations in the quasiparticle self-energy operator within the G W method. This approach, named G W perturbation theory (G W PT), is applied to calculate the electron-phonon (e − ph) interactions with the full inclusion of the G W nonlocal, energy …
