Quantum Fields on Time-Periodic AdS
Walker Melton, Andrew Strominger, Tianli Wang
We consider a free complex massive scalar on the quotient spacetime AdS, which has the isometry group SO(2,2) rather than its universal cover. This problem is of int…
No-Boundary State for Klein Space
Walker Melton, Atul Sharma, Andrew Strominger +1
Analytic continuation from signature Minkowski to signature Klein space has emerged as a useful tool for the understanding of scattering amplitudes and flat space h…
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…
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…
