Gravitational spin-orbit coupling in binary systems, post-Minkowskian approximation, and effective one-body theory
Gravitational spin-orbit coupling in binary systems, post-Minkowskian approximation, and effective one-body theory
A novel approach for extracting gauge-invariant information about spin-orbit coupling in gravitationally interacting binary systems is introduced. This approach is based on the ``scattering holonomy'', i.e. the integration (from the infinite past to the infinite future) of the differential spin evolution along the two worldlines of a binary system in …
