Viscosity, Black Holes, and Quantum Field Theory

Son, D. T., Starinets, A. O.

Understand

We review recent progress in applying the AdS/CFT correspondence to finite-temperature field theory.

  • In particular, we show how the hydrodynamic behavior of field theory is reflected in the low-momentum limit of correlation functions computed through a real-time AdS/CFT prescription, which we formulate.
  • We also show how the hydrodynamic modes in field theory correspond to the low-lying quasinormal modes of the AdS black p-brane metric.
  • We provide a proof of the universality of the viscosity/entropy ratio within a class of theories with gravity duals and formulate a viscosity bound conjecture.
