Abstract

We present a microscopic theory for the time resolved light emission from a semiconductor quantum dot, interacting with LO-phonons. We investigate the emission properties of the QD under strong external laser powers, leading to strongly correlated electron phonon dynamics. We employ an equation of motion approach, which treats the electron phonon interaction with necessary accuracy far beyond the typical bath approximation. We can describe several new non-equilibrium features, like phonon assisted Mollowtriplets and phonon related anti-crossings, which occur in the spectrum in the strong excitation regime.
