Anisotropic Extra Dimensions [PDF]

Physical Review D, 2011
We consider the scenario where in a five-dimensional theory, the extra spatial dimension has different scaling than the other four dimensions. We find background maximally symmetric solutions, when the bulk is filled with a cosmological constant and at ...

Disordered Extra Dimensions

New Journal of Physics, 2010
A very large extra dimension may contain many localized branes. We discuss the possibility to formulate such models as a spin system where each spin indicates the supersymmetry direction preserved by the corresponding brane.

Inflation from Extra Dimensions [PDF]

Physics Letters B, 1994
A gravity-driven inflation is shown to arise from a simple higher dimensional universe. In vacuum, the shear of $n>1$ contracting dimensions is able to inflate the remaining three spatial dimensions.

Large Extra Dimensions from a Small Extra Dimension [PDF]

Journal of High Energy Physics, 2001
Models with extra dimensions have changed our understanding of the hierarchy problem. In general, these models explain the weakness of gravity by diluting gravity in a large bulk volume, or by localizing the graviton away from the standard model. In this

Flexible extra dimensions

European Physical Journal C: Particles and Fields, 2023
This paper discusses the origin of the small parameters with the aim of explaining the Hierarchy problem. The flexible extra dimensions are an essential tool in the process by which physical parameters are formed.

Discerning Noncommutative Extra Dimensions [PDF]

Physical Review D, 2002
Experimental limits on the violation of four-dimensional Lorentz invariance imply that noncommutativity among ordinary spacetime dimensions must be small. Noncommutativity among extra, compactified spatial dimensions, however, is far less constrained and

Gravity and Large Extra Dimensions [PDF]

Advances in Astronomy, 2011
The idea that quantum gravity can be realized at the TeV scale is extremely attractive to theorists and experimentalists alike. This proposal leads to extra spacial dimensions large compared to the Planck scale.

The Absorptive Extra Dimensions [PDF]

Physical Review D, 2003
It is well known that gravity and neutrino oscillation can be used to probe large extra dimensions in a braneworld scenario. We argue that neutrino oscillation remains a useful probe even when the extra dimensions are small, because the brane-bulk ...

An Introduction to Extra Dimensions [PDF]

Journal of Physics: Conference Series, 2005
Models that involve extra dimensions have introduced completely new ways of looking up on old problems in theoretical physics. The aim of the present notes is to provide a brief introduction to the many uses that extra dimensions have found over the last

Thick brane in Rastall gravity

Journal of High Energy Physics, 2022
In this work, thick branes in Rastall gravity are investigated. Three types of maximally symmetric thick brane models are constructed and the linear tensor perturbation is analyzed. In the flat brane model, the tensor modes of the perturbation are either
