Shocks and quark-meson scatterings at large density

We discuss the phase structure of the two-flavor quark-meson model including quantum, thermal, density and critical fluctuations with the functional renormalization group. This study combines two technical advances in the literature, that are also chiefly important for the quantitative access of the phase boundary of QCD at large density or baryon-chemical potential. Specifically we allow for the formation and propagation of shocks as well as a fully self-consistent computation of the order parameter potential for chiral symmetry breaking.
