Renormalisation group arguments from Pisarski and Wilczek suggest that the number of light modes recovered as the chiral limit is approached in QCD is different at nonzero baryon densities, and that this regime is delineated by a first-order critical endpoint. It is important to confront these fluctuation-driven deconfinement scenarios with an ab initio nonpeturbative calculation, we comment on recent progress in this determination.
