Abstract
With the exception of confinement the three-dimensional Nambu-Jona-Lasinio (NJL3) model incorporates many of the essential properties of QCD. We discuss the critical properties of the model at non-zero temperature T and/or non-zero chemical potential μ. We show that the universality class of the thermal transition is that of the d = 2 classical spin model with the same symmetry. We provide evidence for the existence of a tricritical point in the (µ,T)-plane. We also discuss numerical results by Hands et al. which showed that the system is critical for µ > µ c and the diquark condensate is zero.
