Sideband mixing in intense laser backgrounds
The electron propagator in a laser background has been shown to be made up of a series of sideband poles. In this paper we study this decomposition by analysing the impact on the sidebands of the residual gauge freedom in the Volkov solution. We show that these gauge transformations do not alter the...
