Abstract

The dynamics of charge and spin currents generated by two-color femtosecond laser pulses is investigated by numerical solutions of the semiconductor Bloch equations. After the coherent excitation, the photocurrents decay due to scattering processes. A non-Markovian treatment of the electron LO-phonon coupling leads to weak oscillations in the current transients.
