The s-qpGW framework unifies electron-phonon and electron-plasmon couplings in a first-principles superconducting treatment, matches Eliashberg results for bulk metals, and correctly predicts no superconductivity in doped monolayer graphene.
Cumulant expansion in the independent-particle approximation accurately calculates charge mobility for weak to moderate electron-phonon coupling in Peierls and Fröhlich models, as validated against Boltzmann and Migdal approaches.
