Abstract

D. T. Son, A. O. Starinets review recent progress in applying the AdS/CFT correspondence to (e&eb) finite-temperature field theory. In particular, they show how the hydrodynamic behavior of field theory is reflected in (e&eb) the low-momentum limit of (e) correlation functions computed through (e&eb) a real-time AdS/CFT prescription, which they formulate. Authors also show how the hydrodynamic modes in field theory correspond to (e&eb) the low-lying quasinormal modes of (e) the AdS black p-brane metric. They provide a proof of the universality of (e) the viscosity/entropy ratio within (eb) a class of theories with (e&eb) gravity duals and formulate (eb) a viscosity bound conjecture. Possible implications for real systems are mentioned.

T. Son, A. O. Starinets STOP Authors study information retrieval from evaporating black holes, assuming that the internal dynamics of a black hole is unitary and rapidly mixing, and assuming that the retriever has unlimited control over the emitted Hawking radiation. If the evaporation of the black hole has already proceeded past the ``half-way'' point, where (e) half of the initial entropy has been radiated away, then (eb) additional quantum information deposited in (eb) the black hole is revealed in (eb) the Hawking radiation very rapidly.
