A spinor representation of Maxwell equations and Dirac equation

Using the Clifford bundle formalism and starting from the free Maxwell equations dF = δF = 0 we show by writing F = bψγ1γ2ψ*, where ψ is a Dirac-Hestenes spinor field, that the Dirac-Hestenes equation (which is the representative of the standard Dirac equation in the Clifford bundle over Minkowski spacetime) is equivalent under general assumptions to those free Maxwell equations. We briefly discuss the implications of our findings for the interpretation of quantum mechanics. 15 refs
