Gravity solutions dual to d-dimensional field theories at finite charge density have a near-horizon region which is AdS2 × R d−1. The scale invariance of the AdS2 region implies that at low energies the dual field theory exhibits emergent quantum critical behavior controlled by a (0+1)-dimensional CFT. This interpretation sheds light on recently-discovered(More)

We study the dispersion relations of mesons in a particular hot strongly coupled su-persymmetric gauge theory plasma. We find that at large momentum k the dispersion relations become ω ≃ v 0 k + a + b/k +. . ., where the limiting velocity v 0 is the same for mesons with any quantum numbers and depends only on the ratio of the temperature to the quark mass T(More)
We search for viable f…R† theories of gravity, making use of the equivalence between such theories and scalar-tensor gravity. We find that models can be made consistent with solar system constraints either by giving the scalar a high mass or by exploiting the so-called chameleon effect. However, in both cases, it appears likely that any late-time cosmic(More)
Fermi liquid theory explains the thermodynamic and transport properties of most metals. The so-called non-Fermi liquids deviate from these expectations and include exotic systems such as the strange metal phase of cuprate superconductors and heavy fermion materials near a quantum phase transition. We used the anti-de-Sitter/conformal field theory(More)

We formulate a holographic Wilsonian renormalization group flow for strongly coupled systems with a gravity dual, motivated by the need to extract efficiently low energy behavior of such systems. Starting with field theories defined on a(More)
We study universal features in the shape dependence of entanglement entropy in the vacuum state of a conformal field theory (CFT) on R 1,d−1. We consider the entangle-ment entropy across a deformed planar or spherical entangling surface in terms of a perturbative expansion in the infinitesimal shape deformation. In particular, we focus on the second order(More)
