چکیده

We show that if the beta functions of a field theory are given by the gradient of a certain potential on the space of couplings, a gravitational background in one more dimension can express the renormalization group (RG) flow of the theory. The field theory beta functions and the gradient flow constraint together reconstruct the second order spacetime equations of motion. The RG equation reduces to the conventional gravitational computation of the spacetime quasilocal stress tensor, and a c-theorem holds true as a consequence of the Raychaudhuri equation. Conversely, under certain conditions, if the RG evolution of a field theory possesses a monotonic c-function, the flow of couplings can be expressed in terms of a higher dimensional gravitational background.

Duality in linearized gravity and holography

We consider spherical gravitational perturbations of AdS4 space-time satisfying general boundary conditions at spatial infinity. Using the holographic renormalization method, we compute the energy-momentum tensor and show that it can always be cast in the form of Cotton tensor for a dual boundary metric. In particular, axial and polar perturbations obeying the same boundary conditions for the e...

Holographic Quantum Critical Transport without Self-Duality

We describe general features of frequency-dependent charge transport near strongly interacting quantum critical points in 2+1 dimensions. The simplest description using the AdS/CFT correspondence leads to a self-dual Einstein-Maxwell theory on AdS4, which fixes the conductivity at a frequency-independent self-dual value. We describe the general structure of higher-derivative corrections to the ...

Migdal’s model and Holography

More than 30 years ago Migdal proposed a model for hadronic resonances based on rational approximants [1]. The final aim was to determine the spectrum of vector mesons in the large-Nc limit which best fulfills quarkhadron duality. The strategy was to start from the short distance behavior of the vector vacuum polarization function < V V > and build the Padé approximant thereof. Migdal further s...

Matching conditions and duality in N=1 SUSY gauge theories in the conformal window.

We discuss duality in N = 1 SUSY gauge theories in Seiberg’s conformal window, (3Nc/2) < Nf < 3Nc. The ’t Hooft consistency conditions – the basic tool for establishing the infrared duality – are considered taking into account higher order α corrections. The conserved (anomaly free) R current is built to all orders in α. Although this current contains all orders in α the ’t Hooft consistency co...

Correlation Functions in Holographic Renormalization Group Flows

We consider the holographic duality for a generic bulk theory of scalars coupled to gravity. By studying the fluctuations around Poincaré invariant backgrounds with nonvanishing scalars, with the scalar and metric boundary conditions considered as being independent, we obtain all oneand two-point functions in the dual renormalization group flows of the boundary field theory. Operator and vev fl...
