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…
