Improved Hydrodynamics from the AdS/CFT

Abstract: (arXiv)
We generalize the (linearized) relativistic hydrodynamics by including all order gradient expansion of the energy momentum tensor, % Only linearized hydrodynamics is considered. %This improved theory is parametrized by four momenta-dependend transport coefficients, one of which is the usual shear viscosity. We then apply the AdS/CFT duality for SUSY in order to compute the retarded correlators of the energy momentum tensor. From the knowledge of these correlators we determine a large set of transport coefficients of third and forth order hydrodynamics. We found that higher order terms have tendency to demenish the effect of viscosity.- 12.38.Mh
