Inclusive Radiation and Backreaction from the Phase-Space S-Matrix
Nathan Moynihan
We develop a phase-space description of classical scattering in which the matter sector of the Dyson S-matrix is partially Weyl transformed while the radiation sector remains opera…
Memory effect from the scattering of Taub-NUT black holes
George Doran, Ricardo Monteiro, Nathan Moynihan
Taub-NUT black holes are somewhat exotic solutions to the vacuum Einstein equations, which have received limited attention in gravitational phenomenology. We use the soft behaviour…
Non-local nonstabiliserness in Gluon and Graviton Scattering
John Gargalionis, Nathan Moynihan, Michael L. Reichenberg Ashby +3
The property of non-stabiliserness, or ``magic'', is of interest in quantum computing due to its role in developing fault-tolerant quantum algorithms with genuine computational adv…
Learning the S-matrix from data: Rediscovering gravity from gauge theory via symbolic regression
Nathan Moynihan
We demonstrate that modern machine-learning methods can autonomously reconstruct several flagship analytic structures in scattering amplitudes directly from numerical on-shell data…
The double copy as a doppelgänger
Nathan Moynihan, Michael L. Reichenberg Ashby, Chris D. White
The double copy relates scattering amplitudes and classical solutions in non-abelian gauge theories and gravity. As such, it is usually expressed in the conventional second-order f…
Spin versus Magic: Lessons from Gluon and Graviton Scattering
John Gargalionis, Nathan Moynihan, Sokratis Trifinopoulos +3
The quantum property of non-stabiliserness, also known as magic, plays a key role in designing quantum computing systems. How to produce, manipulate and enhance magic remains myste…
