Several tens of femtoseconds after optical excitation, scattering processes in semiconductors are not completed, thus, relaxation has not yet become irreversible. This opens the fascinating possibility of actually reversing or enhancing incompleted scattering events. Here, we use attosecond time scale coherent control to suppress or amplify the non-Markovian phonon oscillations in the model semiconductor GaAs. [S0031-9007(98)05370-8].
