Finite-time memory detectors and fully constraining Faddeev-Kulish dressings in QED and gravity
Brett Oertel
We show that for both QED and perturbative quantum gravity, finite-time Faddeev-Kulish dressings can be fully constrained by symmetry, and that this gives the unique choice which r…

Asymptotic charges as detectors and the memory effect in massive QED and perturbative quantum gravity
Brett Oertel, Ian Moult, Sabrina Pasterski
It has been shown that there are an infinite set of asymptotic symmetries in quantum gravity and QED, and this has been extended to dressed states in some cases. Here we rederive t…

Missing local operators, zeros, and twist-4 trajectories
Johan Henriksson, Petr Kravchuk, Brett Oertel
The number of local operators in a CFT below a given twist grows with spin. Consistency with analyticity in spin then requires that at low spin, infinitely many Regge trajectories…
