Semiconductor electron-phonon equations: A rung above Boltzmann in the many-body ladder
Semiconductor electron-phonon equations: A rung above Boltzmann in the many-body ladder
Starting from the ab initio many-body theory of electrons and phonons, we go through a series of well defined simplifications to derive a set of coupled equations of motion for the electronic occupations and polarizations, nuclear displacements as well as phononic occupations and coherences. These are the semiconductor electron-phonon equations …
