Confinement and complex singularities in QED 3


The standard approximations of the Dyson–Schwinger equation lead to complex singularities of the fermion propagator. In three-dimensional QED one can show that this phenomenon might be related to confinement: a confining potential leads to mass-like singularities at complex momenta, and thus to the absence of a mass singularity on the real timelike axis. The correct treatment of the vacuum polarization is essential for the confining nature of QED3. 11.10.Kk,11.15.Pg,11.15.Tk,11.55.Bq Typeset using REVTEX
