Punctuated eternal inflation via AdS/CFT

Lowe, David A., Roy, Shubho

Understand

The work is an attempt to model a scenario of inflation in the framework of Anti de Sit- ter/Conformal Field theory (AdS/CFT) duality, a potentially complete nonperturbative description of quantum gravity via string theory.

  • We look at bubble geometries with de Sitter interiors within an ambient Schwarzschild anti-de Sitter black hole spacetime and obtain a characterization for the states in the dual CFT on boundary of the asymptotic AdS which code the expanding dS bubble.
  • These can then in turn be used to specify initial conditions for cosmology.
  • Our scenario naturally interprets the entropy of de Sitter space as a (logarithm of) subspace of states of the black hole microstates.
