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 \((\mu,T)\)-plane. We also discuss numerical results by Handset al. which showed that the system is critical for \(\mu > \mu_c\) and the diquark condensate is zero.
