Effective theory approach to brane world black holes
Paul L. McFadden, Neil Turok
We derive static spherically-symmetric vacuum solutions of the low-energy effective action for the two brane Randall-Sundrum model. The solutions with non-trivial radion belong to…
Conformal symmetry of brane world effective actions
Paul L. McFadden, Neil Turok
A simple derivation of the low-energy effective action for brane worlds is given, highlighting the role of conformal invariance. We show how to improve the effective action for a p…
The Cyclic Model Simplified
Paul J. Steinhardt, Neil Turok
The Cyclic Model attempts to resolve the homogeneity, isotropy, and flatness problems and generate a nearly scale-invariant spectrum of fluctuations during a period of slow contrac…
A new duality relating density perturbations in expanding and contracting Friedmann cosmologies
Latham A. Boyle, Paul J. Steinhardt, Neil Turok
For a 4-dimensional spatially-flat Friedmann-Robertson-Walker universe with a scalar field , potential and constant equation of state , we show that an expandin…
Beyond Inflation: A Cyclic Universe Scenario
Neil Turok, Paul J. Seinhardt
Inflation has been the leading early universe scenario for two decades, and has become an accepted element of the successful `cosmic concordance' model. However, there are many puz…
