What the inflaton might tell us about RHIC/LHC

Berges, J.

Understand

Topical phenomena in high-energy physics related to collision experiments of heavy nuclei ("Little Bang") and early universe cosmology ("Big Bang") involve far-from-equilibrium dynamics described by quantum field theory.

  • One example concerns the role of plasma instabilities for the process of thermalization in heavy-ion collisions.
  • The reheating of the early universe after inflation may exhibit rather similar phenomena following a tachyonic or parametric resonance instability.
  • Certain universal aspects associated to nonthermal fixed points even quantitatively agree, and considering these phenomena from a common perspective can be fruitful.
