  text: This chapter focuses on the carrier interaction effects—that is, the many-body
    Coulomb correlations and their influence on band-gap semiconductor optical nonlinearities.
    The near band-gap semiconductor response is determined by the optical interaction
    with the resonant or near resonant material polarization that may result in the
    excitation of carriers (electron–hole pairs) and/or transient coherent nonlinearities.
    The microscopic analysis of these effects requires the investigation of the relevant
    quasi-particles and their interactions. Whereas the basic occurrence of a blue
    shift can be motivated already based on a simple two-level model, a more detailed
    understanding of the optical Stark effect in semiconductors requires a microscopic
    modeling of the relevant bands as well as the inclusion of the many-body Coulomb
    interaction. Compensations among the first- and higher-order Coulomb terms at
    the spectral positions of the exciton are obtained in the differential absorption
    induced by incoherent occupations.
