Kerr Black Hole Dynamics from an Extended Polyakov Action
N. Emil J. Bjerrum-Bohr, Gang Chen, Chenliang Su +1
We examine a hypersurface model for the classical dynamics of spinning black holes. Under specific rigid geometric constraints, it reveals an intriguing solution resembling expecta…

Systematic integral evaluation for spin-resummed binary dynamics
Gang Chen, Jung-Wook Kim, Tianheng Wang
Computation of spin-resummed observables in post-Minkowskian dynamics typically involve evaluation of Feynman integrals deformed by an exponential factor, where the exponent is a l…

Dynamics of Spinning Binary at 2PM
Gang Chen, Tianheng Wang
We consider the covariant proposal for the gravitational Compton amplitude for a Kerr black hole. Employing the covariant three- and four-point Compton amplitudes, we assemble the…
