Relativistic viscous hydrodynamics, conformal invariance, and holography
R. Baier, P. Romatschke, D. T. Son +2
We consider second-order viscous hydrodynamics in conformal field theories at finite temperature. We show that conformal invariance imposes powerful constraints on the form of the…
Fluid turbulence and eddy viscosity in relativistic heavy-ion collisions
Paul Romatschke
The eddy viscosity for a turbulent compressible fluid with a relativistic equation of state is derived. Compressibility allows for sound modes, but the eddy viscosity in the shear…
Viscosity Information from Relativistic Nuclear Collisions: How Perfect is the Fluid Observed at RHIC?
Paul Romatschke, Ulrike Romatschke
Relativistic viscous hydrodynamic fits to RHIC data on the centrality dependence of multiplicity, transverse and elliptic flow for sqrt{s}=200 GeV Au+Au collisions are presented. F…
Causal Viscous Hydrodynamics for Central Heavy-Ion Collisions II: Meson Spectra and HBT Radii
Paul Romatschke
Causal viscous hydrodynamic fits to experimental data for pion and kaon transverse momentum spectra from central Au+Au collisions at \sqrt{s_{NN}}=200 GeV are presented. Starting t…
