Holography and quantum states in elliptic de Sitter space
Illan F. Halpern, Yasha Neiman
We outline a program for interpreting the higher-spin dS/CFT model in terms of physics in the causal patch of a dS observer. The proposal is formulated in "elliptic" de Sitter spac…

Higher-spin gravity as a theory on a fixed (anti) de Sitter background
Yasha Neiman
We study Vasiliev's higher-spin gravity in 3+1d. We formulate the theory in the so-called compensator formalism, where the local isometry group SO(4,1) is reduced to the Lorentz gr…

Quantum fields and entanglement on a curved lightfront
Illan Halpern, Yasha Neiman
We consider field quantization on an arbitrary null hypersurface in curved spacetime. We discuss the de Sitter horizon as the simplest example, relating the horizon quantization to…
