Hidden Symmetry in the Double Copy
Adam Ball, Anna Bencke, Yaxi Chen +1
We show that the Killing tensor of the Kerr spacetime has an analogue in the gauge theory solution related to it by the classical double copy. This hidden symmetr…
Global First Laws of Accelerating Black Holes
Adam Ball
We generalize the first law of black hole mechanics to the rotating, charged C-metric and to the Ernst metric, both of which have the charged C-metric as a special case. All of the…
Scattering and the Celestial Torus
Alexander Atanasov, Adam Ball, Walker Melton +2
Analytic continuation from Minkowski space to split signature spacetime has proven to be a powerful tool for the study of scattering amplitudes. Here we show that, under th…
Uplifting AdS3/CFT2 to Flat Space Holography
Adam Ball, Elizabeth Himwich, Sruthi A. Narayanan +2
Four-dimensional (4D) flat Minkowski space admits a foliation by hyperbolic slices. Euclidean AdS3 slices fill the past and future lightcones of the origin, while dS3 slices fill t…
