The dual quark condensate in local and nonlocal NJL models: An order parameter for deconfinement?

We study the behavior of the dual quark condensate Σ1 in the Nambu–Jona-Lasinio (NJL) model and its nonlocal variant. In quantum chromodynamics Σ1 can be related to the breaking of the center symmetry and is therefore an (approximate) order parameter of confinement. The deconfinement transition is t...
