Electrodynamics on κ-Minkowski space-time
In this paper, we derive Lorentz force and Maxwell’s equations on kappa-Minkowski space-time up to the first order in the deformation pa- rameter. This is done by elevating the principle of minimal coupling to non-commutative space-time. We also show the equivalence of minimal coupling prescription and Feynman’s approach. It is shown that the mo- tion in kappa space-time can be interpreted as motion in a background gravitational field, which is induced by this non-commutativity. In the static limit, the effect of kappa deformation is to scale the electric charge. We also show that the laws of electrodynamics depend on the mass of the charged particle, in kappa space-time.
