Gluon Scattering in Expanding de Sitter Universe
Audrey Lindsay, Tomasz R. Taylor
We construct an observer-centric S-matrix in the expanding Poincaré patch of four-dimensional de Sitter space. The asymptotic states are defined along the worldline of a comoving,…

Symmetries of de Sitter Particles and Amplitudes
Audrey Lindsay, Tomasz R. Taylor
We discuss the symmetry aspects of quantum field theory in global four-dimensional de Sitter spacetime linked to isometries. For the unitary irreducible representations r…

On the Learnability of Knot Invariants: Representation, Predictability, and Neural Similarity
Audrey Lindsay, Fabian Ruehle
We analyze different aspects of neural network predictions of knot invariants. First, we investigate the impact of different knot representations on the prediction of invariants an…
