Complete collisions approximation to the Kadanoff-Baym equation: a first principles implementation.

We show carriers dynamics on bulk Silicon in the sub pico second time scale. The results are obtained from a first principles implementation of the the Kadanoff-Baym equations within the generalized Baym-Kadanoff ansatz and the complete collision approximation. The resulting scattering term is similar to the scattering described within the semi classical Boltzmann equation [1].
