چکیده

We consider Kasner space–time describing anisotropic three-dimensional expansion of RHIC and LHC fireball study the generalisation Bjorken’s one-dimensional by taking into account second-order relativistic viscous hydrodynamics. Using time-dependent AdS/CFT correspondence, we late-time behaviour Bjorken flow. From conditions conformal invariance energy–momentum conservation, obtain explicit expression for energy density as a function proper time in terms parameters. The dependence temperature entropy have also been obtained Eddington–Finkelstein-type coordinates discuss gravity dual anisotropically expanding fluid regime.

A Holographic Dual of Hydrodynamics

We consider a gravity dual description of time dependent, strongly interacting large-Nc N = 4 SYM. We regard the gauge theory system as a fluid with shear viscosity. Our fluid is expanding in one direction following the Bjorken’s picture that is relevant to RHIC experiments. We obtain the dual geometry at the late time that is consistent with dissipative hydrodynamics. We show that the integrat...

Second order hydrodynamics of a CFT plasma from boost invariant expansion

We compute finite coupling correction to a nonlinear second order hydrodynamic coefficient in the boost invariant expansion of the N = 4 supersymmetric Yang-Mills plasma. The result is universal for a large class of strongly coupled four dimensional conformal gauge theories.

Hydrodynamics of Holographic Superconductors

We study the poles of the retarded Green functions of a holographic superconductor. The model shows a second order phase transition where a charged scalar operator condenses and a U(1) symmetry is spontaneously broken. The poles of the holographic Green functions are the quasinormal modes in an AdS black hole background. We study the spectrum of quasinormal frequencies in the broken phase, wher...

Causality of Holographic Hydrodynamics

We study causality violation in holographic hydrodynamics in the gauge theory/string theory correspondence, focusing on Gauss-Bonnet gravity. The value of the GaussBonnet coupling is related to the difference between the central charges of the dual conformal gauge theory. We show that, when this difference is sufficiently large, causality is violated both in the second-order truncated theory of...

Second Order Hydrodynamics for a Special Class of Gravity Duals

The sound mode hydrodynamic dispersion relation is computed up to order q 3 for a class of gravitational duals which includes both Schwarzschild AdS and Dp-Brane metrics. The implications for second order transport coefficients are examined within the context of Israel-Stewart theory. These sound mode results are compared with previously known results for the shear mode. This comparison allows ...
