A microscopic many-body theory describing the optical and electronic properties of semiconductors and semiconductor nanostructures is briefly reviewed. At the semiclassical level, the optical response is computed using Maxwell's equations together with the semiconductor Bloch equations which describe the dynamics of the diagonal and the off-diagonal terms of the reduced single-particle density matrix...
Summary form only given. A microscopic many-body theory for the optical and electronic properties of semiconductors is reviewed with an emphasis on the role of correlation effects among the electronic excitations and in the light matter coupling. The nonlinear response near the fundamental absorption edge and the light emission characteristics are studied for a variety of laser excited heterostructure...
