A heavily updated preprint on validating and extending the Feynman variational polaron solution + FHIP mobility theory to real materials.

We find the 60 year old FHIP theory agrees almost perfectly with recent Diagrammatic QMC calculations, and that extending the theory to multiple phonon modes starts to show rich structure in the frequency response of mobility.
