Are you sure its solution is the wf of a relativistic electron? I infer there is no equation for the PHOTON. AG* *Maxwell’s Equations already are relativistic and they already describe the correct degrees of freedom. So quantization of the electromagnetic field automatically results in photons. So there’s no need for a separate photon wavefunction equation.* *But any initial condition for a double slit experiment cannot result in the interference pattern for a free particle, where the probability spreads over time. Regardless of the initial condition, we always get an interference pattern on the screen, which although fixed on the screen and changing along the screen, doesn't yield a spreading probability. So I have no idea what Brent was referring to, when he suggested the initial condition would shed light on this issue.
