Equations of motion in gravity theories with nonminimal coupling: a loophole to detect torsion macroscopically?
Dirk Puetzfeld, Yuri N. Obukhov
We derive multipolar equations of motion for gravitational theories with general nonminimal coupling in spacetimes admitting torsion. Our very general findings allow for the system…
Unraveling gravity beyond Einstein with extended test bodies
Dirk Puetzfeld, Yuri N. Obukhov
The motion of test bodies in gravity is tightly linked to the conservation laws. This well-known fact in the context of General Relativity is also valid for gravitational theories…
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…
On Poincaré gauge theory of gravity, its equations of motion, and Gravity Probe B
Friedrich W. Hehl, Yuri N. Obukhov, Dirk Puetzfeld
Ever since E.Cartan in the 1920s enriched the geometric framework of general relativity (GR) by introducing a {\it torsion} of spacetime, the question arose whether one could find…
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…
Influence of internal structure on the motion of test bodies in extreme mass ratio situations (MG13)
Jan Steinhoff, Dirk Puetzfeld
We present some recent results on the motion of test bodies with internal structure in General Relativity. On the basis of a multipolar approximation scheme, we study the motion of…
