Description
I discuss lattice calculations of the Polyakov loop and of Polyakov loop correlators for QCD with 2+1 flavors and almost physical quark masses using the highly improved staggered quark action (HISQ).
I elucidate how the Polyakov loop and related observables behave in the crossover region and how these observables probe the deconfinement aspects of the crossover.
I examine the short- and long-distance regimes of Polyakov loop correlators and discuss the color-screening in the thermal medium.
I also discuss the onset of weak-coupling behavior at high temperatures and short distances.
