Quasi Gravity in Branes
نویسنده
چکیده
In contrast with pseudo-gravitational effects that are mathematically analogous but physically quite distinct from gravity, this presentation deals with a kind of quasi-gravitational effect that can act in an asymmetrically moving brane world-sheet in a manner that approximates (and in a crude analysis might be physically indistinguishable from) the effect that would arise from genuine gravitation, of ordinary Newtonian type in non-relativistic applications, and of scalar-tensor (Jordan-Brans-Dicke rather than pure Einstein) type in relativistic applications.

Non-linear Gravity on Branes and Effective Action
We develop the general formalism to study the low energy regime of the brane world. We apply our formalism to the single brane model where the AdS/CFT correspondence will take an important role. We also consider the two-brane system and show the system is described by the quasi-scalar tensor gravity. Our result provides a basis for predicting CMB fluctuations in the braneworld models.

The author has previously suggested that the ground state for 4-dimensional quantum gravity can be represented as a condensation of non-linear gravitons connected by Dirac strings. In this note we suggest that the low-lying excitations of this state can be described by a quasi-topological action of the form d z 13 ∫ F 4 ∧ F 5 ∧ F 4 , corresponding to a trilinear coupling of solotonic 8-branes a...
متن کاملLocalizing Gravity on the Triple Intersection of 7-branes in 10D
It was recently proposed that our universe could naturally come to be dominated by 3-branes and 7-branes if the universe is ten-dimensional. In this paper, we explicitly demonstrate that gravity can be localized on the intersection of three 7-branes in AdS10 to give fourdimensional gravity. We derive the exact relations among the tensions of the branes, and show that they apply independently of...
متن کاملGravitational 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 gravitational backreactions of anti-D branes. In order to see the effects of the self-gravity of anti-D branes, a simplified model is studied where a 5-dimensional anti-de Sitter (AdS) spacetime is realized by...
متن کاملD - Branes on the Conifold and N = 1 Gauge / Gravity Dualities ∗
We review extensions of the AdS/CFT correspondence to gauge/ gravity dualities with N = 1 supersymmetry. In particular, we describe the gauge/gravity dualities that emerge from placing D3-branes at the apex of the conifold. We consider first the conformal case, with discussions of chiral primary operators and wrapped D-branes. Next, we break the conformal symmetry by adding a stack of partially...
