  Fluctuations are included in a chiral nucleon-meson model within the
framework of the functional renormalization group. The model, with parameters
fitted to reproduce the nuclear liquid-gas phase transition, is used to study
the phase diagram of QCD. We find good agreement with results from chiral
effective field theory. Moreover, the results show a separation of the chemical
freeze-out line and chiral symmetry restoration at large baryon chemical
potentials.
