Kerr-Newman quasinormal modes and Seiberg-Witten theory
Hector O. Silva, Jung-Wook Kim, M. V. S. Saketh
It was recently suggested the quasinormal-mode spectrum of black holes is related to a class of four-dimensional super Yang-Mills theories described by Seiberg-Witt…
Systematic integral evaluation for spin-resummed binary dynamics
Gang Chen, Jung-Wook Kim, Tianheng Wang
Computation of spin-resummed observables in post-Minkowskian dynamics typically involve evaluation of Feynman integrals deformed by an exponential factor, where the exponent is a l…
Radiation eikonal for post-Minkowskian observables
Jung-Wook Kim
A recent proposal reinterprets the eikonal as the scattering generator, which computes scattering observables through an action as a symmetry generator. The aim of this study is to…
Classical eikonal from Magnus expansion
Joon-Hwi Kim, Jung-Wook Kim, Sungsoo Kim +1
In a classical scattering problem, the classical eikonal is defined as the generator of the canonical transformation that maps in-states to out-states. It can be regarded as the cl…
Absorptive Effects in Black Hole Scattering
Yilber Fabian Bautista, Yu-Tin Huang, Jung-Wook Kim
In this paper we define absorptive Compton amplitudes, which captures the absorption factor for waves of spin-weight- scattering in black hole perturbation theory. At the leadin…
Massive twistor worldline in electromagnetic fields
Joon-Hwi Kim, Jung-Wook Kim, Sangmin Lee
We study the (ambi-)twistor model for spinning particles interacting via electromagnetic field, as a toy model for studying classical dynamics of gravitating bodies including effec…
