Cosmological models with a de Sitter 3-brane embedded in a 5-dimensional de Sitter spacetime (dS{sub 5}) give rise to a finite 4D Planck mass similar to that in Randall-Sundrum (RS) brane-world models in anti-de Sitter 5-dimensional spacetime(AdS{sub 5}). Yet, there arise a few important differences as compared to the results with a flat 3-brane or 4D Minkowski spacetime. For example, the mass reduction formula (MRF) M{sub Pl}{sup 2}=M{sub (5)}{sup 3}l{sub AdS} as well as the relationship M{sub…

De Sitter thin brane model

We discuss the large mass hierarchy problem in a braneworld model which represents our acceleratively expanding universe. The Randall-Sundrum (RS) model with warped one extra dimension added to flat

WE PROBABLY LIVE ON AN INFLATING BRANE-WORLD

Brane-world models, where observers are trapped within the thickness of a 3-brane, offer novel perspectives on gravitation and cosmology. In this essay, it is argued that the problem of a late epoch

Cosmology of a Friedmann-Lamaître-Robertson-Walker 3-brane, late-time cosmic acceleration, and the cosmic coincidence.

It is shown that the cosmology of a Friedmann-Lamaître-Robertson-Walker 3-brane in a five-dimensional anti-de Sitter spacetime with a big bang nucleosynthesis bound on the time variation of the effective Newton constant G(N) is satisfied, which leads to an effective equation of state close to -1 at late epochs in accordance with astrophysical and cosmological observations.

Localization and mass spectra of bulk matter fields on two-field split-branes

In this paper we investigate the localization of the bulk matter fields on twofield split-branes. The branes are generalized by two scalars, a double-kink scalar φ and a dilaton scalar π. For the

q-form fields on p-branes

A bstractIn this paper, we give one general method for localizing any form (q-form) field on p-branes with one extra dimension, and apply it to some typical p-brane models. It is found that, for the

Localization of gravitino field on f(R)-thick branes

In this paper, we consider the localization of a five-dimensional gravitino field on f(R)-thick branes. We obtain the coupled chiral equations of the Kaluza-Klein (KK) modes of gravitinos with the

Gravitational resonances in mimetic thick branes

A bstractIn this work, we investigate gravitational resonances in both single and double mimetic thick branes, which can provide a new way to detect the extra dimension. For the single brane model,

Thick de Sitter 3-branes, dynamic black holes, and localization of gravity

The embedding of a thick de Sitter 3-brane into a five-dimensional bulk is studied, assuming a scalar field with a potential is present in the bulk. A class of solutions is found in closed form that

We address the localization of gravity on the Friedmann-Robertson-Walker type brane embedded in either $AdS_{5}$ or $dS_{5}$ bulk space,and derive two definite limits between which the value of the

We carefully investigate the gravitational equations of the brane world, in which all the matter forces except gravity are confined on the 3-brane in a 5-dimensional spacetime with $Z_2$ symmetry. We
