Abstract in another language

We study the dynamics of a semiconductor quantum dot coupled to phonons and laser light in the limit of strong electronic confinement. Using real time path integrals our numerical results are nonperturbative with respect to both, the carrier-light and the carrier-phonon coupling. As it is known the damping of Rabi rotations is a non-monotonic function of the pulse area.Here, we analyze how pulse parameters affect the resulting decay-reappearance of Rabi rotations, which arises from the resonant nature of carrier-phonon coupling. For longer pulses, the maximal reduction of the amplitude of Rabi rotations is shifted to higher pulse areas. In addition, for Gaussian pulses the reappearance rate is significantly reduced compared to rectangular profiles.
