Numerical solution of nonstationary problems for a space-fractional diffusion equation
Petr N. Vabishchevich
An unsteady problem is considered for a space-fractional diffusion equation in a bounded domain. A first-order evolutionary equation containing a fractional power of an elliptic op…
Spin-torsion coupling and gravitational moments of Dirac fermions: theory and experimental bounds
Yuri N. Obukhov, Alexander J. Silenko, Oleg V. Teryaev
We discuss the quantum dynamics of the Dirac fermion particle in a gauge gravitational field. The minimal as well as the Pauli-type nonminimal coupling of a fermion with external f…
Motion of spinning test bodies in Kerr spacetime
Eva Hackmann, Claus Lämmerzahl, Yuri N. Obukhov +2
We investigate the motion of spinning test bodies in General Relativity. By means of a multipolar approximation method for extended test bodies we derive the equations of motion, a…
Equations of motion in metric-affine gravity: A covariant unified framework
Dirk Puetzfeld, Yuri N. Obukhov
We derive the equations of motion of extended deformable bodies in metric-affine gravity. The conservation laws which follow from the invariance of the action under the general coo…
Conservation laws in gravity: A unified framework
Yuri N. Obukhov, Dirk Puetzfeld
We study general metric-affine theories of gravity in which the metric and connection are the two independent fundamental variables. In this framework, we use Lagrange-Noether meth…
Prospects of detecting spacetime torsion
Dirk Puetzfeld, Yuri N. Obukhov
How to detect spacetime torsion? In this essay we provide the theoretical basis for an answer to this question. Multipolar equations of motion for a very general class of gravitati…
