Spectral function in QED3
Yuichi Hoshino
We discuss the structure of the dressed fermion propagator in unquenched QED3 based on spectral function of photon.In this approximation infrared divergences that appeared in quenc…

Mass singularity and confinement
Yuichi Hoshino
Infrared behaviour of the fermion propagator is examined by spectral representation.Assuming asymptotic states and using LSZ reduction formula we evaluate the the lowest order spec…

A solution to Ward-Takahashi-identity in QED3
Yuichi Hoshino
Using spectral function of photon we find the reliable results for the effects of vacuum polarization for the dressed fermion propagator in three-dimensional QED.
