Observables and Unconstrained Spin Tensor Dynamics in General Relativity from Scattering Amplitudes
Mark Alaverdian, Zvi Bern, Dimitrios Kosmopoulos +4
In a previous Letter, we showed that physical scattering observables for compact spinning objects in general relativity can depend on additional degrees of freedom in the spin tens…

Conservative Spin Magnitude Change in Orbital Evolution in General Relativity
Mark Alaverdian, Zvi Bern, Dimitrios Kosmopoulos +4
We show that physical scattering observables for compact spinning objects in general relativity can depend on additional degrees of freedom in the spin tensor beyond those describe…

Dynamical Implications of the Kerr Multipole Moments for Spinning Black Holes
Trevor Scheopner, Justin Vines
Previously the linearized stress tensor of a stationary Kerr black hole has been used to determine some of the values of gravitational couplings for a spinning black hole to linear…
