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…
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…
Perturbations of General Relativity to All Orders and the General Order Terms
Kyoungho Cho, Kwangeon Kim, Kanghoon Lee
We derive all-order expressions for perturbations of the Einstein-Hilbert action and the Einstein equation with the general -th order terms. To this end, we employ Cheung and Re…
Quantum Off-Shell Recursion Relation
Kanghoon Lee
We construct off-shell recursion relations for arbitrary loop-level scattering amplitudes beyond the conventional tree-level recursion relations for -theory and the Yang-Mil…
Double copying Exceptional Field theories
David S. Berman, Kwangeon Kim, Kanghoon Lee
We examine exceptional field theory through the lens of the generalised double copy formalism. This allows us to construct classical solutions in M-theory using a generalised Kerr-…
