Gaussian Curvature and Gyroscopes [PDF]
Communications on Pure and Applied Mathematics, 2017 We relate Gaussian curvature to the gyroscopic force, thus giving a mechanical interpretation of the former and a geometrical interpretation of the latter. We do so by considering the motion of a spinning disk constrained to be tangent to a curved surface.

Horndeski theories confront the Gravity Probe B experiment
, 2018 In this work we have investigated various properties of a spinning gyroscope in the context of Horndeski theories. In particular, we have focused on two specific situations --- (a) when the gyroscope follows a geodesic trajectory and (b) when it is ...

Gyroscopic gravitational memory
Journal of High Energy Physics, 2023 Abstract We study the motion of a gyroscope located far away from an isolated gravitational source in an asymptotically flat spacetime. As seen from a local frame tied to distant stars, the gyroscope precesses when gravitational waves cross its path, resulting in a net ‘orientation memory’ that carries information on the wave ...
