The Dynamical Generation of Macroscopic Coherent Light
In quantum optics for the theory of the laser commonly only are calculated photon rate equations and the coherence properties of the emitted light are only discussed by the mean and mean-square photon numbers in the single mode approach of the quantized electromagnetic field. In terms of operator algebraic quantum statistical mechanics the present work gives a detailed microscopic description how the coherent laser light is generated during the time evolution in dependence upon the macroscopic preparation of the radiating atoms or molecules. For this we study the extended Dicke model, a very large system of (infinitely many) two-level atoms interacting with the radiation field quantized in the whole euclidean space R3.
