Unitary connection in Maxwell-Dirac isomorphism and the Clifford algebra
The authors consider the massless Dirac equation and Maxwell's equations for a tensor-scalar field. A unitary operator is found which gives an isomorphism between the sets of nullsolutions. Special attention is given to the case of Maxwell's equations with gradient-like currents for which the exact solution containing both transverse and longitudinal components is obtained.
