ABSTRACT

Interrelations of the intrinsic momentum (spin), rotation of material distributions, and intrinsic momentum of the gravitational field are investigated in the context of the general relativistic theory of gravitation involving the general relativity theory (GRT) and the Einstein-Cartan theory. It is demonstrated that the spin density vector of the gravitational field sgi is equal to the rotor of the tetrad reference point ωi=ɛiklm ek(a) e(a)l,m/2 to within the factor 1/κ (sgi=ω/κc). It is demonstrated that the vector sgi is proportional to the spin density vector of the gravitating field si (ω)=jc(Ψγiγ5Ψ)/2 as well as the pseudovector of space-time torsion Qi in the Einstein-Cartan theory, which in both cases induces a cubic nonlinearity of the spinor field. An expression for the energy-momentum density tensor of the eddy gravitational field is derived. It is also demonstrated that the free eddy gravitational field with polarized spin can form “mole holes.” An ideal fast-rotating self-gravitating fluid can cause a similar effect. The corresponding exact solutions of joint systems of the Einstein and rotating ideal fluid equations are presented. More... »
