Abstract in another language

We analyze the decoherence, exciton formation, and relaxation of electron–hole pairs in a GaAs quantum wire following a pulsed optical excitation near the band edge. Within a microscopic density matrix theory the combined dynamics of coherent and incoherent electron–hole pairs in bound as well as in scattering states is studied for excitations below, at, and above the band gap. We account for a variety of scattering mechanisms and discuss related correlation-induced renormalizations of the relaxation properties.
