Description
I discuss in detail the deconfining phase transition in Polyakov's confining model (Georgi-Glashow theory) in 2+1 dimensions. I show that the deconfinement is the same as the restoration of the magnetic $Z_2$ symmetry, and discuss the physical mechanism that drives the transition. The somewhat surprising analogy with the chiral phase transition in QCD suggests that the chiral transition may be mostly due to appearance of baryons and antibaryons in the thermal ensemble.
