Conservation laws in gravitational theories with general nonminimal coupling
Yuri N. Obukhov, Dirk Puetzfeld
We use the Lagrange-Noether methods to derive the conservation laws for models in which matter interacts nonminimally with the gravitational field. The nonminimal coupling function…
Covariant equations of motion for test bodies in gravitational theories with general nonminimal coupling
Dirk Puetzfeld, Yuri N. Obukhov
We present a covariant derivation of the equations of motion for test bodies for a wide class of gravitational theories with nonminimal coupling, encompassing a general interaction…
Dynamics of test bodies with spin in de Sitter spacetime
Yuri N. Obukhov, Dirk Puetzfeld
We study the motion of spinning test bodies in the de Sitter spacetime of constant positive curvature. With the help of the 10 Killing vectors, we derive the 4-momentum and the ten…
Spin dynamics in gravitational fields of rotating bodies and the equivalence principle
Yuri N. Obukhov, Alexander J. Silenko, Oleg V. Teryaev
We discuss the quantum and classical dynamics of a particle with spin in the gravitational field of a rotating source. A relativistic equation describing the motion of classical sp…
Electromagnetic energy and momentum in moving media
Yuri N. Obukhov
The problem of the electromagnetic energy-momentum tensor is among the oldest and the most controversial in macroscopic electrodynamics. In the center of the issue is a dispute abo…
Elie Cartan's torsion in geometry and in field theory, an essay
Friedrich W. Hehl, Yuri N. Obukhov
We review the application of torsion in field theory. First we show how the notion of torsion emerges in differential geometry. In the context of a Cartan circuit, torsion is relat…
