From Big Crunch to Big Bang with AdS/CFT

  title={From Big Crunch to Big Bang with AdS/CFT},
  author={Neil Turok and Ben Craps and Thomas Hertog},
  journal={arXiv: High Energy Physics - Theory},
The AdS/CFT correspondence is used to describe five-dimensional cosmology with a big crunch singularity in terms of super-Yang-Mills theory on R times S^3 deformed by a potential which is unbounded below. Classically, a Higgs field in the dual theory rolls to infinity in finite time. But since the S^3 is finite, the unstable mode spreads quantum mechanically and the singularity is resolved when self-adjoint boundary conditions are imposed at infinity. Asymptotic freedom of the coupling… Expand

Quantum resolution of cosmological singularities using AdS/CFT correspondence
The AdS/CFT correspondence allows us to map a dynamical cosmology to a dual quantum field theory living on the boundary of spacetime. Specifically, we study a five-dimensional model cosmology in typeExpand
AdS crunches, CFT falls and cosmological complementarity
We discuss aspects of the holographic description of crunching AdS cosmologies. We argue that crunching FRW models with hyperbolic spatial sections are dual to semiclassical condensates in deformedExpand

A bstractWe construct simple solutions of three-dimensional higher spin gravity interacting with matter in which only the scalar and spin-two fields are excited. They preserve Lorentz symmetry andExpand
Cosmological singularities encoded in IR boundary correlations
A bstractWe study the dynamics near big crunch singularities produced in asymptotic AdS cosmologies using gauge/gravity duality. The dual description consists of a constant mass deformation of ABJMExpand
Holographic Curvature Perturbations in a Cosmology with a Space-Like Singularity
We study the evolution of cosmological perturbations in an anti-de-Sitter (AdS) bulk through a cosmological singularity by mapping the dynamics onto the boundary conformal fields theory by means ofExpand
Fluctuations in a cosmology with a spacelike singularity and their gauge theory dual description
We consider a time-dependent deformation of anti-de-Sitter (AdS) space-time which contains a cosmological "singularity" - a space-like region of high curvature. Making use of the AdS/CFTExpand
Probing crunching AdS cosmologies
A bstractHolographic gravity duals of deformations of CFTs formulated on de Sitter spacetime contain FRW geometries behind a horizon, with cosmological big crunch singularities. Using a specificExpand
Gauge Theories with Time Dependent Couplings and their Cosmological Duals
We consider the N = 4 super Yang-Mills theory in flat 3 + 1-dimensional space-time with a time dependent coupling constant which vanishes at t = 0, like g 2 YM = t p . In an analogous quantumExpand
Following the primordial perturbations through a bounce with AdS/CFT correspondence
A bounce universe model, known as the coupled-scalar-tachyon bounce (CSTB) universe, has been shown to solve the Horizon, Flatness and Homogeneity problems as well as the Big Bang singularityExpand
