Holographic dual of a boost-invariant plasma with chemical potential
We construct a gravity dual of a boost-invariant flow of an N = 4 SU(N) supersymmetric Yang-Mills gauge theory plasma with chemical potential. We present both a firstorder corrected late-time solution in Eddington-Finkelstein coordinates and a zeroth-order solution in parametric form in Fefferman-Graham coordinates. The resulting background takes the form of a time-dependent AdS Reissner-Nordst...
متن کاملA 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...
متن کاملHydrodynamics 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...
متن کاملCausality 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...
متن کاملBulk viscosity in holographic Lifshitz hydrodynamics
We compute the bulk viscosity in holographic models dual to theories with Lifshitz scaling and/or hyperscaling violation, using a generalization of the bulk viscosity formula derived in arXiv:1103.1657 from the null focusing equation. We find that only a class of models with massive vector fields are truly Lifshitz scale invariant, and have a vanishing bulk viscosity. For other holographic mode...
