A Hopf Algebraic Theory of the Quantum Magnusian

Li Guo, Joon-Hwi Kim, Jung-Wook Kim +3

We develop a Hopf-algebraic theory of graph coefficients arising in the quantum Magnus expansion. At the classical level, the expansion is governed by directed trees, whereas its q…

Gravitational Faraday rotation, gravitational spin Hall effect, and spin-refined causality analysis from Magnusian matrix in effective field theories of gravity

Kibok Jeong, Jung-Wook Kim, Soochang Lee

The effects of black hole's spin in effective field theories (EFTs) of gravity are explored through observables of wave scattering on black hole backgrounds in the geometric optics…

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…

Twisted Feynman Integrals: from generating functions to spin-resummed post-Minkowskian dynamics

Joon-Hwi Kim, Jung-Wook Kim, Jungwon Lim

We propose to call a class of deformed Feynman integrals as twisted Feynman integrals, where the integrand has an additional exponential factor linear in loop momenta. Such integra…

Magnusian: Relating the Eikonal Phase, the On-Shell Action, and the Scattering Generator

Jung-Wook Kim, Raj Patil, Trevor Scheopner +1

Two fundamentally distinct types of quantities are both called "eikonal" in present amplitudes literature. The unitarity of the S-matrix ensures it can be written as the exponentia…

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…

Spin supplementary condition in quantum field theory: covariant SSC and physical state projection

Jung-Wook Kim, Jan Steinhoff

The spin supplementary conditions are constraints on spin degrees of freedom in classical relativity which restricts physical degrees of freedom to rotations. It is argued that the…

The 2PM Hamiltonian for binary Kerr to quartic in spin

Wei-Ming Chen, Ming-Zhi Chung, Yu-tin Huang +1

From the S-matrix of spinning particles, we extract the 2 PM conservative potential for binary spinning black holes up to quartic order in spin operators. An important ingredient i…

The Relativistic Spherical Top as a Massive Twistor

Joon-Hwi Kim, Jung-Wook Kim, Sangmin Lee

We prove the equivalence between two traditional approaches to the classical mechanics of a massive spinning particle in special relativity. One is the spherical top model of Hanso…
