Gauge Independence and Relativistic Electron Dispersion Equation in Dense Media
We discuss the gauge parameter dependence of particle spectra in statistical
quantum electrodynamics and conclude that the electron spectrum is
gauge-parameter dependent. The physical spectrum being obtained in the Landau
gauge, which leads to gauge invariance in a restricted class of gauge
transformations.Comment: Style corrections 16 pages, three figures, RevTe
