Anisotropic transverse flow is studied in Pb + Pb and Au + Au collisions at SPS and RHIC energies. The centrality and transverse momentum dependence at midrapidity of the elliptic flow coefficient v2 is calculated in the hydrodynamic and low density limits. Hydrodynamics is found to agree well with the RHIC data for semicentral collisions up to transverse momenta of 1–1.5 GeV/c, but it considerably overestimates the measured elliptic flow at SPS energies. The low density limit LDL is inconsistent with the measured magnitude of v2 at RHIC energies and with the shape of its pt -dependence at both RHIC and SPS energies. The success of the hydrodynamic model points to very rapid thermalization in Au + Au collisions at RHIC and provides a serious challenge for kinetic approaches based on classical scattering of on-shell particles. 2001 Published by Elsevier Science B.V.

- Theory of ultracold atomic Fermi gases (2007, background): “The anisotropic expansion exhibited by ultracold gases shares important analogies with the expansion observed in the quark gluon plasma produced in heavy ion collisions (see, for example, Kolb et al., 2001; Shuryak, 2004).”
- Observation of long-range, near-side angular correlations in proton-proton collisions at the LHC (2010, background): “…latter case, the observed long-range correlations are generally assumed to arise from various components of hydrodynamic flow of the produced medium [9, 36–39], from interactions between hard scattering processes and the medium, and from collective effects in the initial interaction of the nuclei.”
- Energy loss of a heavy quark moving through Script N = 4 supersymmetric Yang-Mills plasma (2006, background): “The measurement of a large elliptic flow for light hadrons is one of the significant pieces of evidence supporting the claim that the quark-gluon plasma produced in RHIC collisions responds like a nearly ideal fluid with a small mean free path [20–28].”
