一般非最小耦合引力理论中试验体的协变运动方程

Covariant equations of motion for test bodies in gravitational theories with general nonminimal coupling

Dirk Puetzfeld, Yuri N. Obukhov

摘要:

我们提出了一个协变推导的运动方程的测试机构的广泛类的引力理论与非最小耦合,包括一般的相互作用,通过完整的9宇称,甚至曲率不变量。在这种理论中,旋转试验体的运动方程是明确地通过Synge的展开技术导出的。我们的研究结果概括了以前的文献中的结果,并允许一个直接的比较广义相对论运动方程的极-偶极测试机构。

英文摘要:

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 via the complete set of 9 parity-even curvature invariants. The equations of motion for spinning test bodies in such theories are explicitly derived by means of Synge's expansion technique. Our findings generalize previous results in the literature and allow for a direct comparison to the general relativistic equations of motion of pole-dipole test bodies.
