  The Polyakov loop is an order parameter to the confinement-deconfinement
phase transition in pure gluodynamics. Recently a simple phenomenological model
has been proposed to describe the available lattice data for the renormalized
Polyakov loop in the deconfinement phase (hep-ph/0505215). These data exhibit
unequivocal inverse power temperature corrections driven by a dimension two
gluon condensate. The heavy quark free energy is also studied and compared to
lattice data.
