We consider the case of a generic braneworld geometry in the presence of one or more moduli fields (e.g., the dilaton) that vary throughout the bulk spacetime. Working in an arbitrary conformal frame, using the generalized junction conditions of gr-qc/0008008 and the Gauss–Codazzi equations, we derive the effective “induced” on-brane gravitational equations. As usual in braneworld scenarios, th...

In this paper, we will analyze the effects of superlight braneworld perturbative modes on clustering galaxies. present manuscript, use Boltzmann and Tsallis statistical approaches to study large distance modification gravity in braneworld. The impact modified potential galaxies is analyzed both approaches. infinities associated with Newtonian point mass approximation models removed using analyt...

This work investigates the influence of a probe string on complexity braneworld according to CA (Complexity equals action) conjecture within Horndeski gravity. In current study, it is considered that scalar fields source gravity has spatial dependence. addition, our system contains particle moving boundary, which corresponds insertion fundamental in higher dimensional bulk. Such an effect given...

A bstract Recently, boundary conformal field theories (BCFTs) have attracted much attention in the context of quantum gravity. This is because a BCFT can be dual to gravity coupled heat bath CFT, known as island model. On this background, it would interesting explore duality between and braneworld. However, seems challenging problem. The reason although there has been study rational BCFTs, comp...

In the intersecting braneworld models, higher curvature corrections to the Einstein action are necessary to provide a non-trivial geometry (brane tension) at the brane junctions. By introducing such terms in a Gauss-Bonnet form, we give an effective description of localized gravity on the singular delta-function branes. There exists a non-vanishing brane tension at the four-dimensional brane in...
