De Sitter holography and entanglement entropy

  title={De Sitter holography and entanglement entropy},
  author={Xi Dong and Eva M Silverstein and Gonzalo Torroba},
  journal={Journal of High Energy Physics},
A bstractWe propose a new example of entanglement knitting spacetime together, satisfying a series of checks of the corresponding von Neumann and Renyi entropies. The conjectured dual of de Sitter in d + 1 dimensions involves two coupled CFT sectors constrained by residual d-dimensional gravity. In the d = 2 case, the gravitational constraints and the CFT spectrum are relatively tractable. We identify a finite portion of each CFT Hilbert space relevant for de Sitter. Its maximum energy level… Expand

Fluctuations and non-Gaussianity in de Sitter spacetime from holographic entanglement entropy
Using entanglement in dS/CFT correspondence, we show that a 4-dimensional de Sitter spacetime in the bulk fluctuates. We calculated the fluctuations of the entanglement entropy, which backreacts withExpand

It is shown that all Rényi entropies satisfy a similar area law in holographic theories and are given by the areas of dual cosmic branes, a one-parameter generalization of the minimal surface prescription for entanglement entropy. Expand
