Radion and holographic brane gravity

  title={Radion and holographic brane gravity},
  author={Sugumi Kanno and J. Soda},
  journal={Physical Review D},
The low energy effective theory for the Randall-Sundrum two brane system is investigated with an emphasis on the role of the non-linear radion in the brane world. The equations of motion in the bulk is solved using a low energy expansion method. This allows us, through the junction conditions, to deduce the effective equations of motion for the gravity on the brane. It is shown that the gravity on the brane world is described by a quasi-scalar-tensor theory with a specific coupling function…

Kaluza-Klein two brane worlds cosmology at low energy
We study two (4+n)-dimensional branes embedded in (5+n)-dimensional spacetime. Using the gradient expansion approximation, we find that the effective theory is described by (4+n)-dimensional
Cosmology with Radion and Bulk Scalar Field in Two Branes Model
We investigate cosmological evolutions of the bulk scalar field (t) and the radion d(t) in five-dimensional dilatonic two branes model. The bulk potential for the scalar field is taken as the
Low-energy effective theory for a Randall-Sundrum scenario with a moving bulk brane
We derive the low-energy effective theory of gravity for a generalized Randall-Sundrum scenario, allowing for a third self-gravitating brane to live in the 5D bulk spacetime. At zero order the 5D
Low Energy Effective Action for Dilatonic Braneworld —A Formalism for Inflationary Braneworld—
We derive the low energy effective action for the dilatonic braneworld. In the case of the single-brane model, we find the effective theory is described by the Einstein-scalar theory coupled to the
Low Energy Branes, Effective Theory and Cosmology
The low energy regime of cosmological BPS-brane configurations with a bulk scalar field is studied. We construct a systematic method to obtain five-dimensional solutions to the full system of
Gravitational backreaction of anti-D branes in the warped compactification
We derive a low-energy effective theory for gravity with anti-D branes, which are essential to get de Sitter solutions in the type IIB string-warped compactification, by taking account of
The Effective Equation of Motion on the Brane World Gravity
Randall-Sundrum single brane system (RS II) is investigated systematically, with an emphasis of the effective equation of motion on the brane, by using a low energy expansion method (gradient
A note on spherically symmetric, static spacetimes in Kanno–Soda on-brane gravity
Spherically symmetric, static on-brane geometries in the Kanno–Soda (KS) effective scalar–tensor theory of on-brane gravity are discussed. In order to avoid brane collisions and/or an infinite
Fermion localization in higher curvature and scalar–tensor theories of gravity
It is well known that, in a braneworld model, the localization of fermions on a lower dimensional submanifold (say a TeV 3-brane) is governed by the gravity in the bulk, which also determines the
