Recursion Relations for Classical Gravity
Poul H. Damgaard, Kwangeon Kim, Kanghoon Lee
We derive a set of recursion relations for the perturbative evaluation of the scattering of two black holes in Einstein gravity. To illustrate, we solve the equations up to third p…
Binary Black Holes and Quantum Off-Shell Recursion
Kyoungho Cho, Kwangeon Kim, Kanghoon Lee
The quantum off-shell recursion provides an efficient and universal computational tool for loop-level scattering amplitudes. In this work, we present a new comprehensive computatio…
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…
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-…
The Off-Shell Recursion for Gravity and the Classical Double Copy for currents
Kyoungho Cho, Kwangeon Kim, Kanghoon Lee
We construct the off-shell recursion for gravity and the graviton current for the perturbative double field theory (DFT). We first formulate the perturbative DFT, which is equivale…
The Classical Double Copy for M-theory from a Kerr-Schild Ansatz for Exceptional Field Theory
David S. Berman, Kwangeon Kim, Kanghoon Lee
We construct the classical double copy formalism for M-theory. This extends the current state of the art by including the three form potential of eleven dimensional supergravity al…
The Classical Double Copy of a Point Charge
Kwangeon Kim, Kanghoon Lee, Ricardo Monteiro +2
The classical double copy relates solutions to the equations of motion in gauge theory and in gravity. In this paper, we present two double-copy formalisms for relating the Coulomb…
