Description
The plasma generated in heavy ion collisions goes through different phases in its time evolution. While early times right after the collision are governed by far-from equilibrium dynamics, later times are believed to be well described by near-equilibrium dynamics. While these regimes of nonequilibrium are complicated to describe within QCD, effective descriptions such as hydrodynamics provide a viable approach. In addition, holographic descriptions allow access to the full nonequilibrium dynamics. In this presentation, we review three examples of such hydrodynamic approaches and corresponding holographic descriptions: 1) nonequilibrium shear viscosity, 2) propagation of nonequilibrium sound waves, and 3) the nonequilibrium chiral magnetic effect.
