Bouncing Braneworlds Go Crunch!

چکیده
Recently, interesting braneworld cosmologies in the Randall-Sundrum scenario have been constructed using a bulk spacetime which corresponds to a charged AdS black hole. In particular, these solutions appear to ‘bounce’, making a smooth transition from a contracting to an expanding phase. By considering the spacetime geometry more carefully, we demonstrate that generically in these solutions the brane will encounter a singularity in the transition region.

Bouncing Negative-Tension Branes
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 dynamical setting, there is therefore the risk that the boundary brane of negative tension, at whose location the value of the harmonic function is always lowest, can encounter a zero of this harmonic function, correspon...

In [1], KKLT give a mechanism to generate de Sitter vacua in string theory. And recently, the scenario, landscape, is suggested to explain the problem of the cosmological constant. In this scenario, the cosmological constant is a de Sitter vacuum. The vacuum is metastable and would decay into an anti-de Sitter vacuum finally. Then the catastrophe of the big crunch appears. In this paper by conj...
متن کاملBouncing Brane Cosmologies from Warped String Compactifications
We study the cosmology induced on a brane probing a warped throat region in a CalabiYau compactification of type IIB string theory. For the case of a BPS D3-brane probing the Klebanov-Strassler warped deformed conifold, the cosmology described by a suitable brane observer is a bouncing, spatially flat Friedmann-Robertson-Walker universe with timevarying Newton’s constant, which passes smoothly ...
متن کاملPast incompleteness of a bouncing multiverse
According to classical GR, Anti-de Sitter (AdS) bubbles in the multiverse terminate in big crunch singularities. It has been conjectured, however, that the fundamental theory may resolve these singularities and replace them by nonsingular bounces. This may have important implications for the beginning of the multiverse. Geodesics in cosmological spacetimes are known to be past-incomplete, as lo...
متن کاملSimulating Post-L F0 Bouncing by Modeling Articulatory Dynamics
Post-L F0 bouncing (post-L bouncing for short) is a prosodic phenomenon whereby F0 is temporarily raised following a very low pitch. The phenomenon is quite robust, but is not widely known, and it has never been computationally modeled. This paper presents the results of our simulation of the phenomenon by modeling articulatory dynamics. Using the quantitative Target Approximation (qTA) model, ...
