Free-Electron Lasers (FEL) provide coherent and widely tunable radiation of high brilliance. Most theoretical descriptions are based on classical physics in agreement with the experimental results. However, an FEL working in the quantum regime is within reach at the Research Center Dresden-Rossendorf. Substantial theoretical progress has been made to understand quantum effects which are usually suppressed in the classical regime and therefore ignored. This includes two-level behavior, recoil effects, phase diffusion and much more. Based on our earlier work, we take a closer look at the density matrix of the joint system of laser field and electron beam. By this way we will analyze the dynamics of the sub-system of the electrons, in particular, the momentum and position distribution, respectively.
