  We describe results for the confinement-deconfinement phase transition as
predicted by the Nambu--Jona-Lasinio model where the local and quantum Polyakov
loop is coupled to the constituent quarks in a minimal way (PNJL). We observe
that the leading correlation of two Polyakov loops describes the chiral
transition accurately. The effects of the current quark mass on the transition
are also analysed.
