We calculate the linearized metric perturbation corresponding to a massless four-dimensional scalar field, the radion, in a five-dimensional two-brane model of Randall and Sundrum. In this way we obtain the relative strengths of the radion couplings to matter residing on each of the branes. The results are in agreement with the analysis of Garriga and Tanaka of gravitational and Brans-Dicke forces between matter on the branes. We also introduce a model with an infinite fifth dimension and… 

The Radion and the perturbative metric in RS1

We calculate the linearized metric perturbations in the five-dimensional two-brane model of Randall and Sundrum. In a carefully chosen gauge, we write down and decouple Einstein equations for the

Wave function of the radion with BPS branes

We investigate coupled gravity and a bulk scalar field on a slice of AdS5 bulk with special BPS branes at the two ends. With a careful treatment of the general coordinate invariance, the complete

Metric Fluctuations in Brane Worlds

Recently, a realization of the four-dimensional gravity on a brane in fivedimensional spacetime has been discussed. Randall and Sundrum have shown that the equation for the longitudinal components of

Gravity in the stabilized brane world model in the five-dimensional Brans-Dicke theory

We obtain and solve the linearized equations of motion for gravity and scalar fields in the world stabilized brane model in the five-dimensional Brans-Dicke theory. We segregate the physical degrees

Cosmology of brane models with radion stabilization

We analyze the cosmology of the Randall-Sundrum model and that of compact brane models in general in the presence of a radius stabilization mechanism. We find that the expansion of our Universe is

GRAVITATIONAL TRAPPING FOR EXTENDED EXTRA DIMENSION

The solution of Einstein's equations for 4-brane embedded in five-dimensional Anti-de Sitter space–time is found. It is shown that the cosmological constant can provide the existence of ordinary

Gravity in brane world

We present a brief review on gravity in brane world. We mainly focus on the Randall‐Sundrum (RS) infinite brane world and Dvali‐Gabadadze‐Porrati (DGP) brane world. Our interest is in non‐linear

An Alternative to compactification

Conventional wisdom states that Newton's force law implies only four noncompact dimensions. We demonstrate that this is not necessarily true in the presence of a nonfactorizable background geometry.
