Torsion nonminimally coupled to the electromagnetic field and birefringence
In conventional Maxwell–Lorentz electrodynamics, the propagation of light is influenced by the metric, not, however, by the possible presence of a torsion T . Still the light can feel torsion if the latter is coupled nonminimally to the electromagnetic field F by means of a supplementary Lagrangian of the type ∼ l2T 2 F 2 (l = coupling constant). Recently Preuss suggested a specific nonminimal ...
متن کاملHow does the electromagnetic field couple to gravity , in particular to metric , nonmetricity , torsion , and curvature ?
The coupling of the electromagnetic field to gravity is an age-old problem. Presently, there is a resurgence of interest in it, mainly for two reasons: (i) Experimental investigations are under way with ever increasing precision, be it in the laboratory or by observing outer space. (ii) One desires to test out alternatives to Einstein’s gravitational theory, in particular those of a gauge-theor...

متن کاملRelativistic Particle with Torsion and Charged Particle in a Constant Electromagnetic Field: Identity of Evolution
The identity of classical motion is established for two physically different models, one of which is the relativistic particle with torsion, whose action contains higher derivatives and which is the effective system for the statistically charged particle interacting with the Chern-Simons U(1) gauge field, and another is the (2+1)dimensional relativistic charged particle in external constant ele...
متن کاملHelicity and the Electromagnetic Field
The structure of the Poincaré group gives, under all conditions, an equation of field helicity which reduces to the Maxwell equations and also gives cyclic relations between field components. If the underlying symmetry of special relativity is represented by the Poincaré group, it follows that the Maxwell equations and the cyclic equations are both products of special relativity itself, and bot...
