From Big Crunch to Big Bang with AdS/CFT
Neil Turok, Ben Craps, Thomas Hertog
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 w…
Horizons and Tunneling in the Euclidean False Vacuum
Kate Marvel, Neil Turok
In the thin-wall approximation, the decay of a gravitating false vacuum to a lower-energy state is affected by the cosmological horizon structure in both spaces. The nucleation rad…
Bouncing Negative-Tension Branes
Jean-Luc Lehners, Neil Turok
Braneworlds, understood here as double domain wall spacetimes, can be described in terms of a linear harmonic function, with kinks at the locations of the boundary branes. In a dyn…
Stringy corrections to a time-dependent background solution of string and M-Theory
Gustavo Niz, Neil Turok
We consider one of the simplest time-dependent backgrounds in M-theory, describing the shrinking away of the M-theory dimension with the other spatial dimensions static. As the M-t…
Primordial Black Hole Baryogenesis
Daniel Baumann, Paul J. Steinhardt, Neil Turok
We reconsider the possibility that the observed baryon asymmetry was generated by the evaporation of primordial black holes that dominated the early universe. We present a simple d…
Generating Ekpyrotic Curvature Perturbations Before the Big Bang
Jean-Luc Lehners, Paul McFadden, Neil Turok +1
We analyze a general mechanism for producing a nearly scale-invariant spectrum of cosmological curvature perturbations during a contracting phase preceding a big bang, that can be…
