A search for the minimal unified field theory. II.Spinor matter and gravity
Abstract
The spin connections of the Dirac field have three ingredients that are connected with the Ricci rotations, the Maxwell field, and an axial field which is coupled to the axial current. I demonstrate that the axial field provides an effective mechanism of autolocalization of the Dirac field into compact objects. A nonlinear system of Dirac and sineGordon equations that has a potential to yield a mass spectrum is derived. The condition that the compact objects are stable (the energymomentum is selfadjoint) leads to the Einstein's field equations. The Dirac field with its spin connection seem to be a natural material carrier of the spacetime continuum in which the compact objects are moving along the geodesic lines. The long distance effect of the axial field is indistinguishable from the Newton's gravity which reveals the microscopic nature of gravity and the origin of the gravitational mass.
