Abstract
The light‐induced changes of the properties of a semiconductor caused by an ultra‐short strong laser pulse with a central frequency well below the fundamental absorption edge are investigated. Renormalization and time evolution of one‐ and two‐particle properties are discussed using a nonequilibrium Green's function formalism. Numerical results for the absorption spectra are presented.Keywords
