摘要：

We theoretically estimate the possibility of detectable coherence effects in nonlinear femtosecond pump-and-probe absorption spectroscopy of semiconductors at high excitation energies and densities by hybridizing the quantum mechanical equations of motion for the intraband and interband density matrices of the photoexcited carriers with an ensemble Monte Carlo simulation of the detailed scattering dynamics. We predict realizable experimental scenarios for Rabi-type oscillations in the transient absorption change at the excitation frequency.
