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…
Symplectic Perturbation Theory in Massive Ambitwistor Space: A Zig-Zag Theory of Massive Spinning Particles
Joon-Hwi Kim, Sangmin Lee
We develop a theory of massive spinning particles interacting with background fields in four spacetime dimensions in which holomorphy and chirality play a central role. Applying a…
Quantum trace map for 3-manifolds and a 'length conjecture'
Prarit Agarwal, Dongmin Gang, Sangmin Lee +1
We introduce a quantum trace map for an ideally triangulated hyperbolic knot complement . The map assigns a quantum operator to each element of Kauffmann…
The Relativistic Spherical Top as a Massive Twistor
Joon-Hwi Kim, Jung-Wook Kim, Sangmin Lee
We prove the equivalence between two traditional approaches to the classical mechanics of a massive spinning particle in special relativity. One is the spherical top model of Hanso…
