A Celestial Dual for MHV Amplitudes
Walker Melton, Atul Sharma, Andrew Strominger +1
It is shown that a 2D CFT consisting of a central charge Liouville theory, a chiral level one, rank Kac-Moody algebra and a weight free fermion holographically gener…
Soft Algebras for Leaf Amplitudes
Walker Melton, Atul Sharma, Andrew Strominger
Celestial MHV amplitudes are comprised of non-distributional leaf amplitudes associated to an AdS leaf of a foliation of flat spacetime. It is shown here that the leaf amplitud…
Conformal Correlators on the Lorentzian Torus
Walker Melton, Atul Sharma, Andrew Strominger
The general form of a 2D conformal field theory (CFT) correlator on a Euclidean Riemann surface, Lorentzian plane or Lorentzian cylinder is well-known. This paper describes the gen…
Hyperbolic Vacua in Minkowski Space
Walker Melton, Filip Niewinski, Andrew Strominger +1
Families of Lorentz, but not Poincare, invariant vacua are constructed for a massless scalar field in 4D Minkowski space. These are generalizations of the Rindler vacuum with a lar…
