      abstract     = {We present a highly parallelisable scheme for treating
                      functional Renormalisation Group equations which
                      incorporates a quasi-particle-based feedback on the flow and
                      provides direct access to real-frequency self-energy data.
                      This allows to map out the boundaries of Fermi-liquid
                      regimes and to study the effect of quasi-particle
                      degradation near Fermi liquid instabilities. As a first
                      application, selected results for the two-dimensional
                      half-filled perfectly nested Hubbard model are shown.},
