The use of a lattice-space Weyl–Wigner formalism of quantum dynamics of particles in solids, coupled with the nonequilibrium Green's function technique, provides a rigorous and straightforward derivation of an exact integral form of the equation for a quantum-distribution function in many-body quantum transport theory. This formulation leads to a straightforward and fully gauge-invariant derivation of the exact quantum transport equation of a uniform electron-phonon scattering system in high electric fields which do not involve any gradient expansion. The resulting expressions serve to generalize previous results.
