Query: Numerical integration of thermal noise in relativistic hydrodynamics   Thermal fluctuations affect the dynamics of systems near critical points, the
evolution of the early universe, and two-particle correlations in heavy-ion
collisions. For the latter, numerical simulations of nearly-ideal, relativistic
fluids are necessary. The correlation functions of noise in relativistic fluids
are calculated, stochastic integration of the noise in 3+1-dimensional viscous
hydrodynamics is implemented, and the effect of noise on observables in
heavy-ion collisions is discussed. Thermal fluctuations will cause significant
variance in the event-by-event distributions of integrated v2 while changing
average values even when using the same initial conditions, suggesting that
including thermal noise will lead to refitting of the hydrodynamical parameters
with implications for understanding the physics of hot QCD.
