The Celestial Chiral Algebra of Self-Dual Gravity on Eguchi-Hanson Space
Roland Bittleston, Simon Heuveline, David Skinner
We consider the twistor description of classical self-dual Einstein gravity in the presence of a defect operator wrapping a certain . The backreaction of this defect…
Moyal deformations, and celestial holography
Wei Bu, Simon Heuveline, David Skinner
We consider the Moyal deformation of self-dual gravity. In the conformal primary basis, holomorphic collinear limits of the amplitudes of this theory show that it enjoys a perturba…
Quantizing the non-linear graviton
Roland Bittleston, Atul Sharma, David Skinner
We consider holomorphic Poisson-BF theory on twistor space. Classically, this describes self-dual Einstein gravity on space-time, but at the quantum level it is plagued by an anoma…
Ambitwistor Strings in Six and Five Dimensions
Yvonne Geyer, Lionel Mason, David Skinner
Ambitwistor strings are chiral (holomorphic) strings whose target is the space of complex null geodesics, ambitwistor space. We introduce twistor representations of ambitwistor spa…
Twistors, the ASD Yang-Mills equations, and 4d Chern-Simons theory
Roland Bittleston, David Skinner
We show that the approaches to integrable systems via 4d Chern-Simons theory and via symmetry reductions of the anti-self-dual Yang-Mills equations are closely related, at least cl…
Ambitwistor Strings and the Scattering Equations on AdSS
Kai Roehrig, David Skinner
We construct an ambitwistor string that describes Type II supergravity on AdSS with pure NS flux. The background Einstein equations ensure that the model is anomaly f…
