Kurzbeschreibung (Abstract)
We present first results on the calculation of fermionic spectral functions from analytically continued flow equations within the functional renormalization group approach. Our method is based on the same analytic continuation from imaginary to real frequencies that was developed and used previously for bosonic spectral functions. In order to demonstrate the applicability of the method also for fermionic correlations we apply it here to the real-time quark propagator in the quark-meson model and calculate the corresponding quark spectral functions in the vacuum.
