  text: The ultrafast dynamics of optical excitations in semiconductors and semiconductor
    nanostructures can be computed on a microscopic theoretical basis using the semiconductor
    Bloch equations. This set of equations allows one to nonperturbatively evaluate
    light-field-induced intraband and interband excitations and is also well suited
    for the analysis of many-body effects such as excitonic resonances and carrier-carrier
    and carrier-phonon scattering processes. In this article we start with a description
    of an experimental observation of coherent spin photocurrents, then we briefly
    introduce the theoretical approach and review some results of our theory concerning
    the microscopic description of the ultrafast coherent optical generation and the
    temporal decay of charge and spin currents in semiconductor nanostructures. The
    computed transients show an enhanced damping of the spin current relative to the
    charge current as a consequence of Coulomb scattering between carriers with opposite
    spin. The influence of quantum kinetic memory effects on the dynamics of the photocurrents
    is analyzed by evaluating the scattering terms beyond the Markov approximation.
