Conformal Bulk Fields

چکیده
We consider in the Randall-Sundrum scenario the dynamics of a spherically symmetric 3-brane world when matter fields exist in the bulk. We determine exact 5-dimensional solutions which localize gravity near the brane and describe the dynamics of homogeneous polytropic matter on the brane. We show that these geometries are associated with a well defined conformal class of bulk matter fields. We analyze the effective polytropic dynamics on the brane identifying conditions which define it as singular or as globally regular. PACS numbers: 04.50.+h, 04.70.-s, 98.80.-k, 11.25.Mj

Conformal Bulk Fields, Dark Energy and Brane Dynamics
In the Randall-Sundrum scenario we analyze the dynamics of a spherically symmetric 3-brane when the bulk is filled with matter fields. Considering a global conformal transformation whose factor is the Z2 symmetric warp we find a new set of exact dynamical solutions for which gravity is bound to the brane. The set corresponds to a certain class of conformal bulk fields. We discuss the geometries...

We give a group-theoretic interpretation of the AdS/CFT correspondence as relation of representation equivalence between representations of the confor-mal group describing the bulk AdS fields φ, their boundary fields φ 0 and the coupled to the latter boundary conformal operators O. We use two kinds of equivalences. The first kind is equivalence between the representations describing the bulk fi...

متن کاملTft Construction of Rcft Correlators Iv: Structure Constants and Correlation Functions
We compute the fundamental correlation functions in two-dimensional rational conformal field theory, from which all other correlators can be obtained by sewing: the correlators of three bulk fields on the sphere, one bulk and one boundary field on the disk, three boundary fields on the disk, and one bulk field on the cross cap. We also consider conformal defects and calculate the correlators of...
متن کاملLocal Fields on the Brane Induced by Nonlocal Fields in the Bulk
We investigate quantum field theory in a bulk space with boundary, which represents a 3-brane. The basic idea is to keep locality (microcausality) only on the brane, giving up this requirement in the bulk. We explore the consequences of this proposal, constructing a large family of nonlocal bulk fields, whose brane relatives are local. We estimate the ultraviolet behavior of these local brane f...
