dc.description The electronic Hamiltonian is used to derive the equations of motion for the one-band density matrix in the six-dimensional configuration space. Projecting the Hamiltonian onto a local basis makes it possible to decompose the Coulomb interaction into a contact and a monopole - monopole part. An approach is presented which allows us to identify the two parts as scattering terms and self-consistent fields in the limiting case of the Boltzmann transport equation. The approach does not assume spatial homogeneity and includes (i) the self-consistent field and (ii) local electron - electron collision terms and (iii) permits us in the extension to a two-band model to incorporate consistently impact ionization in a form analogous to the electron - electron scattering term.
