On universality of stressenergy tensor correlation functions in supergravity [rapid communication]
Abstract
Using the Minkowski space AdS/CFT prescription we explicitly compute in the lowenergy limit the twopoint correlation function of the boundary stressenergy tensor in a large class of type IIB supergravity backgrounds with a regular translationally invariant horizon. The relevant set of supergravity backgrounds includes all geometries which can be interpreted via gauge theory/string theory correspondence as being holographically dual to finite temperature gauge theories in Minkowski spacetimes. The fluctuationdissipation theorem relates this correlation function computation to the previously established universality of the shear viscosity from supergravity duals, and to the universality of the low energy absorption cross section for minimally coupled massless scalars into a general spherically symmetric black hole. It further generalizes the latter results for the supergravity black brane geometries with nonspherical horizons.
