Dark energy, Dirac's scalar field and the cosmological constant problem
O. V. Babourova, B. N. Frolov
The solutions of the field equations of the conformal theory of gravitation with Dirac scalar field in Weyl-Cartan spacetime in very early universe are obtained. In this theory dar…
Interaction of the 4-rotational gauge field with orbital momentum, gravidiamagnetic effect, and orbit experiment "Gravity Probe B"
Olga V. Babourova, Boris N. Frolov
The direct interaction of the 4-rotational (Lorentzian) gauge field with the angular orbital momentum of an external field is considered. This interaction appears in a new Poincaré…
Perfect hypermomentum fluid: variational theory and equations of motion
Olga V. Babourova, Boris N. Frolov
The variational theory of the perfect hypermomentum fluid is developed. The new type of the generalized Frenkel condition is considered. The Lagrangian density of such fluid is sta…
Matter with dilaton charge in Weyl-Cartan spacetime and evolution of the Universe
Olga V. Babourova, Boris N. Frolov
The perfect dilaton-spin fluid (as a model of the dilaton matter, the particles of which are endowed with intrinsic spin and dilaton charge) is considered as the source of the grav…
Plane torsion waves in quadratic gravitational theories
O. V. Babourova, B. N. Frolov, E. A. Klimova
The definition of the Riemann-Cartan space of the plane wave type is given. The condition under which the torsion plane waves exist is found. It is expressed in the form of the res…
Perfect fluid and test particle with spin and dilatonic charge in a Weyl-Cartan space
O. V. Babourova, B. N. Frolov
The equation of perfect dilaton-spin fluid motion in the form of generalized hydrodynamic Euler-type equation in a Weyl-Cartan space is derived. The equation of motion of a test pa…
