TLDR
In this article, the authors consider an especially simple version of a thick domain wall in AdS space and investigate how four-dimensional gravity arises in this context, and demonstrate that there are no such resonances in the model they consider.About:

Self-tuning flat domain walls in 5D gravity and string theory
TL;DR: In this paper, the authors present Poincare-invariant domain wall (''three-brane'') solutions to some five-dimensional effective theories which can arise naturally in string theory.
Journal ArticleDOI
Thick brane solutions
TL;DR: In this article, a comprehensive review on brane solutions and related topics is presented. But, the authors do not consider the brane world model in this paper, and they only consider the case of two interacting scalar fields.

General properties of the self-tuning domain wall approach to the cosmological constant problem
Csaba Csáki,Joshua Erlich,Christophe Grojean,Christophe Grojean,Timothy J. Hollowood,Timothy J. Hollowood +5 more
TL;DR: In this article, the authors study the dynamics of brane worlds coupled to a scalar field and gravity, and find that self-tuning of the cosmological constant is generic in theories with at most two branes or a single brane with orbifold boundary conditions.

TL;DR: In this paper, the authors investigate a system described by two real scalar fields coupled with gravity in (4, 1) dimensions in warped spacetime involving one extra dimension and show that the parameter which controls the way the two scalar field interact induces the appearence of thick brane which engenders internal structure, driving the energy density to localize inside the brane in a very specific way.
Journal ArticleDOI
Thick domain walls and singular spaces
TL;DR: In this paper, the authors discuss thick domain walls interpolating between spaces with naked singularities and give arguments based on the AdS/CFT correspondence why such singularities may be physically meaningful.

An Alternative to compactification
TL;DR: In this paper, a single 3-brane embedded in five dimensions was shown to reproduce four-dimensional Newtonian and general relativistic gravity to more than adequate precision, even without a gap in the Kaluza-Klein spectrum.
Journal ArticleDOI
Modulus stabilization with bulk fields
TL;DR: A mechanism for stabilizing the size of the extra dimension in the Randall-Sundrum scenario is proposed and the minimum of this potential yields a compactification scale that solves the hierarchy problem without fine-tuning of parameters.

The Einstein equations on the 3-brane world
Tetsuya Shiromizu,Tetsuya Shiromizu,Keiichi Maeda,Keiichi Maeda,Misao Sasaki,Misao Sasaki,Misao Sasaki +6 more
TL;DR: In this paper, the authors consider the brane world with a negative tension and derive the effective gravitational equations, which reduce to the conventional Einstein equations in the low energy limit, in which all the matter forces except gravity are confined on the 3-brane in a 5-dimensional spacetime with ${Z}_{2}$ symmetry.
Journal ArticleDOI
Modeling the fifth dimension with scalars and gravity
TL;DR: In this article, a method for obtaining solutions to the classical equations for scalars plus gravity in five dimensions is applied to some recent suggestions for brane-world phenomenology, which involves only first order differential equations.

Brane cosmological evolution in a bulk with cosmological constant
TL;DR: In this article, the authors considered the cosmology of a 3-brane universe with a cosmological constant and showed that the Friedmann equation admits a first integral, analogous to the first Friedmann equations, which governs the evolution of the metric in the brane.
