The Conformal -Algebra
Simon Heuveline, Nia Robles Del Pino, Andrew Strominger
Einstein gravity in four asymptotically flat dimensions is governed by a tower of soft theorems obeying an commutator algebra. This algebra is deformed to…
Self-Dual Yang-Mills in AdS
Simon Heuveline, Romain Ruzziconi, Ahmed Sheta +1
Quantum Yang-Mills theory in Euclidean AdS with Neumann boundary conditions is studied as a function of the complex couplings $\frac{1}{g_\pm^2} \equiv \frac{1}{g^2}\mp \frac{i…
Non-Commutative Gauge Theory at the Beach
Roland Bittleston, Simon Heuveline, Surya Raghavendran +1
The KP equation is perhaps the most famous example of a three-dimensional integrable system. Here we show that a non-commutative five-dimensional Chern-Simons theory living on the…
Celestial Chiral Algebras and Self-Dual Gravity
Simon Heuveline
Celestial holography suggests, among other things, that collinear singularities of graviton scattering amplitudes are described by the OPEs of some putative dual CFT. One of the gr…
Towards celestial chiral algebras of self-dual black holes
Giuseppe Bogna, Simon Heuveline
In this note, we show that several self-dual spacetimes previously studied in the context of celestial and twisted holography arise as limits of a certain Taub-NUT AdS metric,…
On AdS deformations of celestial symmetries
Roland Bittleston, Giuseppe Bogna, Simon Heuveline +3
Celestial holography has led to the discovery of new symmetry algebras arising from the study of collinear limits of perturbative gravity amplitudes in flat space. We explain from…
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…
