Abstract

On the lattice we study the gauge boson propagator of three-dimensional compact QED in the Landau gauge at zero and nonzero temperature. The nonperturbative effects are taken into account by the generation of a mass, by an anomalous dimension, and by photon wave function renormalization. All these effects can be attributed to the monopoles: they are absent in the propagator of the singularity-free part of the gauge field. We assess carefully the Gribov copy problem for the propagator and the parameters emerging from the fits.
