Quantum Theory of Quantum Dot Emission — •Lukas Schneebeli, Thomas Feldtmann, Mackillo Kira, and Stephan W. Koch — Department of Physics and Material Sciences Center, Philipps-Universität Marburg

The microscopic theory of semiconductor quantum dots is formulated including Coulomb interaction and quantum optical coupling effects. Several examples of optical excitations are evaluated using the generalized semiconductor Bloch and luminescence equations [1,2]. Absorption and photoluminescence spectra are discussed for several quantum dot realizations.
