Hello
I'm trying to understand how much freedom one has to pick a gauge to use for gauge fixing a free EM field and if so, on what conditions that freedom depends.
Is there a particular reason (besides Lorentz covariance) to pick the Lorenz gauge? Are the alternatives (R[itex]\xi[/itex] for instance) still meaningful?
