Power spectrum of flow fluctuations in relativistic heavy-ion collisions
  We carry out hydrodynamical simulation of the evolution of fluid in
relativistic heavy-ion collisions with random initial fluctuations. The time
evolution of power spectrum of momentum anisotropies shows very strong
correspondence with the physics of cosmic microwave anisotropies as was earlier
predicted by some of us. In particular our results demonstrate suppression of
superhorizon fluctuations and the correspondence between the location of the
first peak in the power spectrum of momentum anisotropies and the length scale
of fluctuations and expected freezeout time scale (more precisely, the sound
horizon size at freezeout).
