Relativistic Noise

Understand

The relativistic theory of hydrodynamic fluctuations, or noise, is derived and applied to high energy heavy ion collisions.

• These fluctuations are inherent in any space-time varying system and are in addition to initial state fluctuations.
• We illustrate the effects with the boost-invariant Bjorken solution to the hydrodynamic equations.
• Long range correlations in rapidity are induced by propagation of sound modes.
