A second order differential equation for the relativistic description of electrons and photons
A new relativistic description of quantum electrodynamics is presented.
Guideline of the theory is the Klein-Gordon equation, which is reformulated to
consider spin effects. This is achieved by a representation of relativistic
vectors with a space-time algebra made up of Pauli matrices and hyperbolic
numbers. The algebra is used to construct the differential operator of the
electron as well as the photon wave equation. The properties of free electron
and photon states related to this wave equation are investigated. Interactions
are introduced as usual with the minimal substitution of the momentum
operators. It can be shown that the new wave equation is equivalent to the
quadratic form of the Dirac equation. Furthermore, the Maxwell equations can be
derived from the corresponding wave equation for photons.Comment: Reverted preprint to initial version of 1999. Most of the content has
been published under the new title "Relativistic quantum physics with
hyperbolic numbers". However, interesting parts like the second quantization
of fermion fields within a Klein-Gordon theory, which is only possible with
the help of hyperbolic or bicomplex numbers, dropped out of the revised
