Abstract:

The identification of attractor behavior offers some hope a conceptually straightforward albeit simplified picture of quark-gluon plasma physics following a relativistic heavy-ion collision. The strong longitudinal expansion which characterizes the dynamics -at least in some model systems- leads to attractor behavior already at very early times. This expansion-driven universality makes it possible to connect features of the system at asymptotically small times to observables that reflect late time physics. I will review some of these developments, including recent work aiming at exploring features of early-times. I will also describe recent attempts to reformulate this circle of ideas in a way that would offer hope of going beyond the boost-invariance assumption which underlies the aforementioned studies.
