A note on gravity-scalar fluctuations in holographic RG flow geometries
We study five-dimensional gravity models with non-vanishing background scalar fields which are dual to non-conformal boundary field theories. We develop a procedure to decouple the graviton fluctuations from the scalar ones and apply it to the simplest case of one scalar field. The quadratic action for the decoupled scalar fluctuations has a very simple form and can be used to compute two-point...
متن کاملScalar fields , bent branes , and RG flow
This work deals with braneworld scenarios driven by real scalar fields with standard dynamics. We show how the first-order formalism which exists in the case of four dimensional Minkowski space-time can be extended to de Sitter or anti-de Sitter geometry in the presence of several real scalar fields. We illustrate the results with some examples, and we take advantage of our findings to investig...
متن کاملRG-Flow, Gravity, and the Cosmological Constant
We study the low energy effective action S of gravity, induced by integrating out gauge and matter fields, in a general class of RS-type string compactification scenarios with exponential warp factors. Our method combines dimensional reduction with the holographic map between between 5-d supergravity and 4-d large N field theory. Using the classical supergravity approximation, we derive a flow ...
متن کاملNote on Holographic RG Flow in String Cosmology
We propose a new holographic C-function for the accelerating universe defined in the stringy frame motivated mainly by the fact that the number of degrees of freedom should be infinite for a physically infinite universe. This is the generalization of Strominger’s recent proposal of the holographic C-function to the asymptotically non-de Sitter universe. We find that the corresponding C-theorem ...
متن کاملAn Exact Holographic RG Flow Between 2d Conformal Fixed Points
We describe a supersymmetric RG flow between conformal fixed points of a two-dimensional quantum field theory as an analytic domain wall solution of the three-dimensional SO(4)×SO(4) gauged supergravity. Its ultraviolet fixed point is an N=(4, 4) superconformal field theory related, through the double D1-D5 system, to theories modeling the statistical mechanics of black holes. The flow is drive...
