Viscosity information from relativistic nuclear collisions: how perfect is the fluid observed at RHIC?
TL;DR: Relativistic viscous hydrodynamic fits to Brookhaven Rel ativistic Heavy Ion Collider data on the centrality dependence of multiplicity, transverse, and elliptic flow for square root s = 200 GeV Au+Au collisions seem to favor a much smaller viscosity over entropy ratio, below the bound from the anti-de Sitter conformal field theory conjecture.
Journal ArticleDOI
Relativistic viscous hydrodynamics, conformal invariance, and holography
TL;DR: In this article, the second-order viscous hydrodynamics in conformal field theories at finite temperature was considered and conformal invariance imposes powerful constraints on the form of second-orders corrections.
Journal ArticleDOI
Conformal relativistic viscous hydrodynamics: Applications to RHIC results at s NN =200 GeV
Matthew Luzum,Paul Romatschke +1 more
TL;DR: In this paper, a new set of equations for relativistic viscous hydrodynamics that captures both weak coupling and strong coupling physics to second order in gradients has been developed.

New Developments in Relativistic Viscous Hydrodynamics
TL;DR: In this paper, relativistic viscous hydrodynamics can directly be solved numerically and the resulting fluid dynamic equations are shown to be consistent for all these derivations when properly accounting for the respective region of applicability, and can be applied to both weakly and strongly coupled systems.
