Optically induced coherence effects in `artificial atoms and molecules'

摘要

Using a master-equation approach for the description of coherent andincoherent dynamics in `artificial atoms and molecules', we present atheoretical analysis of situations where intense laser fields lead topronounced renormalizations of carrier states. Such enhanced light-matterinteractions allow for the solid-state implementation of effects hitherto onlyobservable in atomic systems. Two prototypical examples will be presented:first, we show how two intense laser pulses can be exploited for a robust andhigh-fidelity population transfer of carrier states in coupled quantum dots;second, we discuss the possibility of observing self-induced transparency in asample of inhomogenously broadened quantum dots, a phenomenon where intenselaser pulses propagate without suffering significant losses.
