Abstract (english)

We investigate the rapid rise of the dressed Polyakov loop in the Nambu–Jona-Lasinio (NJL) model as a function of temperature. In QCD such a behavior is interpreted as a confinement-deconfinement phase transition. However, we demonstrate that in the NJL model this is simply a remnant of the chiral transition.
