  text: A number of experiments yielded a polarization-dependent decay of the time-integrated
    four-wavemixing (TI-FWM). Often, the TI-FWM decays more rapidly for linear perpendicular
    than for linear parallel polarized incident pulses. It was suspected that this
    difference in the decay times is related to the inhomogeneous linewidth of the
    exciton, i.e. to disorder [1], On the other hand, it was demonstrated in a large
    number of recent publications, that the understanding of polarization-dependent
    FWM and pump-probe experiments following excitonic excitation requires the treatment
    of Coulomb correlations beyond the Hartree-Fock level. For not too strong disorder,
    these correlations still remain important and influence the nonlinear optical
    response [2]. A meaningful analysis of disorder effects thus has to include correlations.

  text: Polarization dependent excitonic absorption changes have been studied recently
    for excitation with weak pump pulses [1]. It was shown, that for both resonant
    and off-resonant excitation even in the low-intensity χ(3)-limit many-body Coulomb
    correlations strongly contribute the optical response [1]. Here we investigate,
    how the coherent pump-induced absorption changes vary with the pump intensity,
    by analyzing the next higher, i.e. the fifth-order contributions.

  text: by inherent disorder effects. Inhomogeneous broadening is the most obvious
    consequence of disorder and an inhomogeneously broadened exciton line might be
    considered as a superposition of homogeneously broadened subensembles of excitons.
    However, a possible coherent coustructures and lead to effects like disorder induced
    dephasing [1].
