Sequential build-up of quantum-optical correlations

The build-up dynamics of quantum-optical correlations in a Jaynes-Cummings model for semiconductor quantum-dot systems is characterized using the cluster-expansion scheme. Assuming an excitation with a coherent state source under strong-and weak-coupling conditions, it is found that higher-order correlations are sequentially generated. Even though the influence of dephasing hinders their development, significant correlations build up even in the presence of strong dissipation showing that quantum-spectroscopy studies are possible even in interacting many-body systems like semiconductors.
