Abstract in another language

Abstract Based on the time-dependent Hartree–Fock equations we study many-body effects in the absorption spectra as well as temporally and spectrally resolved four-wave-mixing signals of modulation-doped quantum well structures. For sufficiently long dephasing times we find a beating behavior in the time-reolved signals related to the Coulomb enhancement.
