Iterative Solution of the Kerr Black Hole Metric
Poul H. Damgaard, Hojin Lee, Kanghoon Lee +1
Using a recursive solution of the Einstein equations, we consider the perturbative expansion of the metric corresponding to a Kerr black hole. Because the metric is a function of t…
Gravitational Metric of a Star
Poul H. Damgaard, Hojin Lee, Kanghoon Lee +1
Solving the classical equations of motion in general relativity recursively, we consider the metric of a spatially localized and stationary source of matter. Having in mind a star…
Classical eikonal in relativistic scattering
Sungsoo Kim, Hojin Lee, Sangmin Lee
The classical eikonal is defined to be the generator of all scattering observables in a scattering problem in classical mechanics. It was originally introduced as the log of the qu…
Poincaré generators at second post-Minkowskian order
Hojin Lee, Kanghoon Lee, Sangmin Lee
We verify the global Poincaré invariance of the Hamiltonian mechanics of gravitating binary dynamics at the second post Minkowskian (2PM) order. For spinless point particles, based…
Poincaré invariance of spinning binary dynamics in the post-Minkowskian Hamiltonian approach
Hojin Lee, Sangmin Lee
We initiate the construction of the global Poincaré algebra generators in the context of the post-Minkowskian Hamiltonian formulation of gravitating binary dynamics in isotropic co…
Classical observables from partial wave amplitudes
Hojin Lee, Sangmin Lee, Subhajit Mazumdar
We study the formalism of Kosower-Maybee-O'Connell (KMOC) to extract classical impulse from quantum amplitude in the context of the partial wave expansion of a 2-to-2 elastic scatt…
