Turbulent thermalization process in high-energy heavy-ion collisions — •Soeren Schlichting — Brookhaven National Lab, Upton, NY USA

The past decades of heavy-ion physics have revealed remarkable properties of the Quark Gluon Plasma formed in collider experiments at RHIC and the LHC. However, the question of how these features emerge ab initio in a heavy-ion collision, and to what extent a thermalized Quark Gluon Plasma is achieved is an outstanding problem in theoretical physics. In this talk I will address the problem of thermalization of the Quark Gluon Plasma from a weak- coupling perspective, where classical-statistical real-time lattice simulations can be employed as a first-principle approach to study the non-equilibrium dynamics. Most remarkably, we find that the thermalization process is governed by a universal attractor, where the evolution becomes insensitive to the details of the initial conditions. Instead, the system exhibits the self-similar dynamics characteristic of wave turbulence, as observed in a large variety of strongly correlated many-body systems across different energy scales.
