Observables for study of the deconfinement transition
The deconfinement transition is typically studied using the Polyakov loop,
which needs renormalization. We look at the renormalization of Polyakov loop
using Wilson flow, for both quenched and $N_f=2$ QCD. We also investigate
some observables related to the Polyakov loop that has been suggested, and
the behavior of the gluon condensate across the transition.
