RG flows and the holographic c - function
We consider holographic RG flows which interpolate between non-trivial ultraviolet (UV) and infra-red (IR) conformal fixed points. We study the " superpo-tentials " which characterize different flows and discuss their expansions near the fixed points. Then we focus on the holographic c-function as defined from the two-point function of the stress-energy tensor. We point out that the equation fo...
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...
متن کاملHolographic RG Flow on the Defect and g-Theorem
We investigate relevant deformation and renormalization group flow in a defect conformal field theory from the point of view of holography. We construct a supersymmetric D5brane solution which represents an RG flow, by deforming anAdS4×S brane inAdS5×S. Our new solution corresponds to the mass deformation of the defect CFT. We also propose a candidate of g-function in the context of holography,...
متن کاملThe Holographic RG flow to conformal and non - conformal theory ∗
We review some aspects of the AdS supergravity description of RG flows. The case of a flow to an IR CFT can be rigorously studied within the framework of supergravity. Here we discuss various central charges of the conformal theory (included the usually neglected ones) and we compare them with QFT expectations. The case of flows to non-conformal theories is more problematic in that one usually ...
