Nonmetricity and hypermomentum: on the possible violation of Lorentz invariance
Yuri N. Obukhov, Friedrich W. Hehl
We outline how the symmetry groups of spacetime are interpreted in a gauge-theoretic approach. Specifically, we focus on the hypermomentum concept and discuss the hyperfluid, that…
Hyperfluid model revisited
Yuri N. Obukhov, Friedrich W. Hehl
A new variational theory of a hyperfluid is constructed which is free of the supplementary condition issue and provides a consistent model of the classical matter source in the met…
Spin as a probe of axion physics in general relativity
Yuri N. Obukhov
The dynamics of spin in external electromagnetic, gravitational, and axion fields is analysed in the framework of the gravitoelectromagnetism approach in Einstein's general relativ…
Spin-Gravity Coupling in a Rotating Universe
Bahram Mashhoon, Masoud Molaei, Yuri N. Obukhov
The coupling of intrinsic spin with the nonlinear gravitomagnetic fields of Goedel-type spacetimes is studied. We work with Goedel-type universes in order to show that the main fea…
Search for manifestations of spin-torsion coupling
Mariya Iv. Trukhanova, Pavel Andreev, Yuri N. Obukhov
We investigate the axial vector torsion-spin coupling effects in the framework of the Poincaré gauge theory of gravity with the general Yang-Mills type Lagrangian. The dynamical eq…
On parity-odd sector in metric-affine theories
Jose Beltrán Jiménez, Alejandro Jiménez-Cano, Yuri N. Obukhov
We undertake the construction of quadratic parity-violating terms involving the curvature in the four-dimensional metric-affine gravity. We demonstrate that there are only 12 linea…
