摘要：

The heavy quark potential in the continuum theory at finite temperature is calculated in different phases by using the Polyakov loop as the order parameter. We find a linearly rising potential in the confinement phase, a Debye screened potential in the deconfinement phase and a perturbative r-2 dependence at very high temperatures. Within the approximation used in this paper we report evidence for a first order phase transition accompanied by SU(2) symmetry restoration at very high temperatures in the static three dimensional theory.
