Worldline formalism in phase space
Joon-Hwi Kim
We implement the worldline formalism in phase space to compute scattering amplitudes. First, the Feynman rules exhibit several useful universal features, reflecting elements of the…

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…

Generalized Symmetry in Dynamical Gravity
Clifford Cheung, Maria Derda, Joon-Hwi Kim +3
We explore generalized symmetry in the context of nonlinear dynamical gravity. Our basic strategy is to transcribe known results from Yang-Mills theory directly to gravity via the…
