Abstract

The control of quantum beats by two phase-locked optical pulses is analyzed theoretically. We compare the case of heavy-light hole quantum beats as an example of a purely electronic coherence with the case of phonon quantum beats which are a characteristic feature of electron-phonon quantum kinetics. The maxima and minima of the beat amplitudes can be understood by the same arguments. For the case of phonon quantum beats an exacly solvable model is presented which allows us to analyze the role of the electron-phonon coupling constant.
