Abstract
Several tens of femtoseconds after optical excitation, scattering proc esses in semiconductors are not completed, thus, relaxation has not ye t become irreversible. This opens the fascinating possibility of actua lly 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].
