TL;DR
This study investigates the photon propagator in 3D compact QED on the lattice, revealing non-perturbative effects like mass generation and anomalous dimensions linked to monopoles, at both zero and finite temperatures.
Contribution
It provides the first lattice analysis of the gauge boson propagator in 3D cQED, highlighting monopole effects on non-perturbative phenomena.
Findings
Mass generation in the photon propagator due to monopoles
Presence of an anomalous dimension alpha
Differences between regular and monopole-induced parts
Abstract
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.
