The fluctuation-dissipation theorem requires the presence of thermal noise in viscous fluids. The time and length scales of heavy ion collisions are small enough so that the thermal noise can have a measurable effect on observables. Thermal noise is included in numerical simulations of high energy lead-lead collisions, increasing average values of the momentum eccentricity and contributing to its event by event fluctuations.

  1. Critical fluid dynamics in two and three dimensions

    nucl-th 2024-11 conditional novelty 6.0 of 10

    Direct numerical simulations of stochastic model H give a dynamic critical exponent z ≈ 3 in 3D and z ≈ 2 in 2D, with a crossover from mean-field z = 4 controlled by the renormalized shear viscosity.

    Derives diffusion matrix elements for baryon, charge, and strangeness transport in relativistic hydrodynamics from entropy production within the relaxation-time approximation.
