CONFINEMENT, DECONFINEMENT AND THE PHOTON PROPAGATOR IN 3D cQED ON THE LATTICE
M. N. CHERNODUB, E.-M. ILGENFRITZ, A. SCHILLER · 2003
We report on a lattice study of the gauge boson propagator of 3D compact QED in Landau gauge at zero and finite temperature. Non-perturbative effects are reflected by the generation of a mass m and by an anomalous dimension alpha. These effects can be attributed to monopoles and are absent in the propagator of the regular part of the gauge field.
