Locally Localized Gravity
We study the fluctuation spectrum of linearized gravity around non-fine-tuned branes. We focus on the case of an AdS4 brane in AdS5. In this case, for small cosmological constant, the warp factor near the brane is essentially that of a Minkowski brane. However, far from the brane, the metric differs substantially. The space includes the AdS5 boundary, so it has infinite volume. Nonetheless, for...
متن کاملLocally Localized Gravity Models in Higher Dimensions
We explore the possibility of generalizing the locally localized gravity model in five space-time dimensions to arbitrary higher dimensions. In a space-time with negative cosmological constant, there are essentially two kinds of higher-dimensional cousins which not only take an analytic form but also are free from the naked curvature singularity in a whole bulk space-time. One cousin is a trivi...
متن کاملLocally Localized Gravity: The Inside Story
We derive the exact gravitational field of a relativistic particle localized on an AdS 3-brane, with curvature radius l, in AdS5 bulk with radius L. The solution is a gravitational shock wave. We use it to explore the dynamics of locally localized tensor gravitons over a wide range of scales. At distances below L the shock wave looks exactly like the 5D GR solution. Beyond L the solution approx...
متن کاملLocally Localized Gravity and Geometric Transitions
In this paper we analyze the local localization of gravity in AdS4 thick brane embedded in AdS5 space. The 3-brane is modelled by domain wall solution of a theory with a bulk scalar field coupled to five-dimensional gravity. In addition to small four-dimensional cosmological constant, the vacuum expectation value (vev) of the scalar field controls the emergence of a localized four-dimensional q...
متن کاملAntisymmetric Tensor Fields in the Locally Localized Gravity Models
We study the localization property of antisymmetric tensor fields in the locally localized gravity models. It is shown that all the antisymmetric tensor fields, including the vector field, in a bulk space-time are trapped on an AdS brane by a gravitational interaction where the presence of the brane cosmological constant plays an important role as in the cases of the other bulk fields. The norm...
