The pure dephasing of the optical polarization and the corresponding line shape of absorption spectra in small quantum dots due to the interaction of the exciton both with optical and acoustic… Expand

The authors review the physics of ultrafast dynamics in semiconductors and their heterostructures, including both the observed experimental phenomena and the theoretical description of the processes.… Expand

The carrier dynamics in semiconductor nanostructures on ultrashort timescales exhibits a variety of phenomena which cannot be understood on a semiclassi-cal level based completely on the particle… Expand

It is found that the phonon-induced damping of Rabi rotations is a nonmonotonic function of the laser field that is increasing at low fields and decreasing at high fields, which results in a reappearance of RBI rotations at high field.Expand

The application of femtosecond spectroscopy to the study of ultrafast dynamics in semiconductor materials and nanostructures is reviewed with particular emphasis on the physics that can be learned… Expand

We report on Rabi oscillations of the biexciton in a single ${\mathrm{In}}_{x}{\mathrm{Ga}}_{1\ensuremath{-}x}\mathrm{As}∕\mathrm{Ga}\mathrm{As}$ quantum dot, induced via a coherent two-photon… Expand

The nonlinear response of single GaAs quantum dots is studied in femtosecond near-field pump-probe experiments, providing the first evidence for a perturbed free induction decay of the excitonic polarization.Expand

A model of semiconductor quantum dots coupled to phonons and laser light, which is relevant in the limit of strong electronic confinement, is investigated. For an arbitrary sequence of excitations by… Expand
