A combined theoretical and experimental analysis of the resonant Rayleigh scattering by excitons in a disordered GaAs quantum well with monolayer islands is reported. Experimentally, the coherent resonant Rayleigh scattering is deduced by means of bo

Summary form only given. While ultrafast semiconductor spectroscopy has investigated scattering times, i.e. the time between different scattering events, for many years, quantum kinetics asks for the duration of one scattering process, i.e. for the m

The dynamic nonequilibrium properties of a crystal electron coupled to a bath of dispersionless phonons are investigated for the strong coupling regime. The four-wave mixing experiments on the semiconductor ZnSe at T=77 K use blue optical pulses of 1

The determination of microscopic optical properties of an ensemble of localized excitons in a solid-state environment using speckle analysis of their resonant light scattering is reviewed. Time-resolved and spectrally resolved variants of the speckle

The resonant Rayleigh scattering dynamics of excitons in single GaAs quantum wells is investigated. The deviation of the measured intensity from the ideal ensemble average is analyzed as a function of the speckle ensemble size. The influence of the a

The resonant light scattering dynamics of multiple GaAs quantum wells measured by speckle averaged spectral interferometry shows a strong and fast initial component not present for single wells which is attributed to radiative coupling.

In Quantum Kinetics, a few tens of femtoseconds after optical excitation, scattering processes in semiconductors are not completed, thus relaxation has not yet become irreversible. Here we review recent experiments on bulk GaAs, GaAs quantum wells an
