P.M. Lo, E.S. Swanson
TL;DR
This paper investigates infrared divergences in massless QED3 at finite temperature, showing they are endemic but do not impact physical observables and can be managed through gauge choices.
Contribution
It reveals the presence of endemic infrared divergences in QED3 and demonstrates a gauge choice that renders the theory finite without affecting observables.
Findings
Infrared divergences are endemic in massless QED3 at finite temperature.
These divergences do not influence physical observables.
A gauge can be chosen to make the theory finite.
Abstract
We demonstrate that massless QED in three dimensions contains endemic infrared divergences. It is argued that these divergences do not affect observables; furthermore, it is possible to choose a gauge that renders the theory finite.
