An unified theory of quantised electrons, phonons and photons out-of-equilibrium: a simplified {\em ab-initio} approach based on the Generalised Baym-Kadanoff ansatz

Pedro Melo, Andrea Marini

We present a full ab-inito description of the coupled out-of-equilibrium dynamics of photons, phonons, and electrons. In the present approach the quantised nature of the electromag…
