  We discuss the phase structure of the two-flavour quark-meson model including
quantum, thermal, density and critical fluctuations with the functional
renormalisation 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.
