We calculate the drag and diffusion coefficients in low temperature QED
plasma and go beyond the leading order approximation. The non-Fermi-liquid
behavior of these coefficients are clearly revealed. We observe that the
subleading contributions due to the exchange of soft transverse photon in both
cases are larger than the leading order terms coming from the longitudinal
sector. The results are presented in closed form at zero and low temperature.
