Topological defects with electromagnetic + gravitomagnetic interactions
Jarek Duda (Jagiellonian U)
Abstract: Classical electromagnetism has two weaknesses: Gauss law allows for non-integer charges, and infinite energy of electric field of a charge. I will start with Faber's model repairing both: defining electric field as curvature of a deeper vector field Gauss law counts topological charge which is quantized, Higgs-like potential deforms the field to finite energy, also getting tiny Coulomb corrections in agreement with the running coupling effect. Then I will discuss its Landau-de Gennes-like extension to field of 3x3 matrices, among others adding low energetic O(1) degree of freedom resembling quantum phase, governed by Klein-Gordon-like dynamics. Finally extending to 4D tensor field adds dynamics governed by second set of Maxwell equations as in gravitoelectromagnetic approximation of the general relativity.
