Projection operator formalism for temporal relaxation phenomena in nanostructures — •Nikolaos Gortsas and Andreas Knorr — Institute for Theoretical Physics, Nonlinear Optics and Quantum Electronics, Technical University Berlin, Germany

By the use of projection operator techniques (POT) we investigate temporal relaxation phenomena in semiconductor nanostructures. POT provide powerful tools to derive close and local master equations of open quantum systems, which allow a systematic description of the non-Markovian features of the dynamics of open quantum systems. We are going to present applications of this theory for quantum dots and intersubband transitions with emphasis on the coupling of the electronic system to a reservoir of phonons.
