I will start with Faber's model repairing both: definin g electric field as curvature of a deeper vector field Gauss law counts to pological charge which is quantized\, Higgs-like potential deforms the fie ld to finite energy\, also getting tiny Coulomb corrections in agreement w ith the running coupling effect. Then I will discuss its Landau-de Gennes- like extension to field of 3x3 matrices\, among others adding low energeti c O(1) degree of freedom resembling quantum phase\, governed by Klein-Gor don-like dynamics. Finally extending to 4D tensor field adds dynamics gove rned by second set of Maxwell equations as in gravitoelectromagnetic appro ximation of the general relativity.\n LOCATION:https://researchseminars.org/talk/QMFNoT/39/ END:VEVENT END:VCALENDAR
