Description

QCD at large densities exhibits a moat regime in the scalar-pseudoscalar sector. The resolution of its dynamics is pivotal for the access to the onset of new phases including the potential critical endpoint of QCD. I report on a first self-consistent analysis of this regime, using the functional Renormalisation Group approach to QCD.Mapping out the moat regime, we find a potential inhomogeneous instability at baryon chemical potential $\mu_B \gtrsim$ 600 MeV on the chiral crossover line. I discuss the stability of the instability together with the closely connected phenomenon of precondensation.
