Micromanaging de Sitter holography

Dong, Xi, Horn, Bart, Silverstein, Eva et al.

Understand

We develop tools to engineer de Sitter vacua with semi-holographic duals, using elliptic fibrations and orientifolds to uplift Freund-Rubin compactifications with CFT duals.

  • The dual brane construction is compact and constitutes a microscopic realization of the dS/dS correspondence, realizing d-dimensional de Sitter space as a warped compactification down to (d-1)-dimensional de Sitter gravity coupled to a pair of large-N matter sectors.
  • This provides a parametric microscopic interpretation of the Gibbons-Hawking entropy.
  • We illustrate these ideas with an explicit class of examples in three dimensions, and describe ongoing work on four-dimensional constructions.
