Asymptotic charges, large gauge transformations and inequivalence of different gauges in external current QED
Abstract In this paper we consider external current QED in the Coulomb gauge and in axial gauges for various spatial directions of the axis. For a non-zero electric charge of the current, we demonstrate that any two different gauges from this class correspond to quantum theories which are not unitar...
