Expanding cosmologies in brane geometries [PDF]
Physical Review D, 2004 Five dimensional gravity coupled, both in the bulk and on a brane, to a scalar Liouville field yields a geometry confined to a strip around the brane and with time dependent scale factors for the four geometry. In various limits known models can be recovered as well as a temporally expanding four geometry with a warp factor falling exponentially away ...

New horizons in the holographic conformal phase transition
European Physical Journal C: Particles and FieldsWe describe 5D dynamical cosmological solutions of the stabilized holographic dilaton and their role in completion of the conformal phase transition. This analysis corresponds, via the AdS/CFT dictionary, to a study of out-of-equilibrium dynamics where ...

, 2010 Despite the nice features of the Dvali, Gabadadze and Porrati (DGP) model to explain the late-time acceleration of the universe, it suffers from some theoretical problems like the ghost issue.

The cosmological impact of Brane-Chern-Simons massive gravity
Journal of High Energy PhysicsIn this paper, we present a novel extension of massive gravity theory; the Brane-Chern-Simons massive gravity theory. We explore the cosmological implications of this theory by deriving the background equations and demonstrating the existence of self ...

The effects of curvature correction terms on brane cosmology
, 2004 We study the cosmology of the Randall-Sundrum brane-world where the Einstein-Hilbert action is modified by curvature correction terms: a four-dimensional scalar curvature from induced gravity on the brane, and a five-dimensional Gauss-Bonnet curvature ...

Quasinormal ringing of de Sitter braneworlds
Journal of High Energy PhysicsCompared with the Poincaré braneworld, the de Sitter (dS) braneworld aligns more closely with the present universe characterized by a small but finite cosmological constant.

Sterile neutrino shortcuts in asymmetrically warped extra dimensions
European Physical Journal C: Particles and Fields, 2019 Light sterile neutrinos are a popular extension of the Standard Model and are being discussed as a possible explanation for various neutrino oscillation anomalies, including the LSND, MiniBooNE, Reactor and Gallium anomalies.
