On the integrability of root-Kerr probe dynamics
Sungsoo Kim, Sangmin Lee
In the background of a Kerr-Newman black hole, the motion of a scalar particle is integrable by virtue of an extra conserved charge known as Carter charge. When the particle is end…
The Diagrammar of Quantum Magnusian
Li Guo, Joon-Hwi Kim, Jung-Wook Kim +3
The logarithm of the time-evolution operator has been termed Magnusian, on account of the fact that its expansion describes the Magnus series. The diagrammatic expansion and comput…
Universality in Relativistic Spinning Particle Models
Joon-Hwi Kim, Sangmin Lee
We establish an equivalence between massive spinning particle models in four spacetime dimensions coupled to electromagnetism or gravity, within the spin-magnitude-preserving secto…
Classical eikonal in relativistic scattering
Sungsoo Kim, Hojin Lee, Sangmin Lee
The classical eikonal is defined to be the generator of all scattering observables in a scattering problem in classical mechanics. It was originally introduced as the log of the qu…
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…
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…
