Parity violation in Poincaré gauge gravity
Yuri N. Obukhov
We analyse the parity violation issue in the Poincaré gauge theory of gravity for the two classes of models which are built as natural extensions of the Einstein-Cartan theory. The…
Temporal Splitting algorithms for non-stationary multiscale problems
Yalchin Efendiev, Sai-Mang Pun, Petr N. Vabishchevich
In this paper, we study temporal splitting algorithms for multiscale problems. The exact fine-grid spatial problems typically require some reduction in degrees of freedom. Multisca…
Gravitational waves in metric-affine gravity theory
Alejandro Jiménez-Cano, Yuri N. Obukhov
We derive the exact gravitational wave solutions in a general class of quadratic metric-affine gauge gravity models. The Lagrangian includes all possible linear and quadratic invar…
Peculiar chemical bonding between thorium and a carbon hexagon in carbon nanomaterials
A. V. Bibikov, A. V. Nikolaev, E. V. Tkalya
We explore an unusual nature of chemical bonding of the thorium atom with a ring of six carbon atoms (hexagon) in novel carbon materials. Our ab initio calculations of Th-based met…
Generalized Birkhoff theorem in the Poincaré gauge gravity theory
Yuri N. Obukhov
The analysis of the validity of Birkhoff's theorem about the uniqueness of the spherically symmetric solution of the gravitational field equations is extended to the framework of t…
General relativity as a special case of Poincaré gauge gravity
Yuri N. Obukhov, Friedrich W. Hehl
We demonstrate that Einstein's general relativity theory arises as a special case in the framework of the Poincaré gauge theory of gravity under the assumption of a suitable nonmin…
