Abstract

A theory of the nonlinear interaction between a single quantum dot (QD) and electromagnetic fields, accounting the QD-depolarization (local-field) has been developed. QD excitation by classical and quantum electromagnetic fields such as coherent state of light, Fock qubit and gaussian excitation has been considered. As a result, for the case of the QD illuminated by coherent states of light, we predict the appearance of two oscillatory regimes in the Rabi oscillations. In the first one, signatures of Rabi oscillations are found to be suppressed: the population inversion is negative and the conventional collapse-revivals phenomenon is absent, while in the second one the collapse and revivals are appeared, showing significant difference as compared to those predicted within the standard Jaynes-Cummins theory. Under the pulsed excitation, Rabi oscillation dynamics is found to be strongly depended on the input pulse area and duration.
