Maximilian Attems (Wien):
Chromo-Weibel plasma instabilities in Bjorken expansion
Abstract:
Non-Abelian plasma instabilities play a
crucial role in the non-equilibrium dynamics of a weakly coupled quark-gluon plasma.
At very early times in the evolution of the heavy ion collisions one assumes an
anisotropic momentum distribution. The generalization of stationary anisotropic plasmas
using the so-called hard-loop approximation to the hard-expanding-loop (HEL) formalism
allows the (numerical) calculation of the full 3-dimensional (configuration space) time
evolution of gluonic mean fields in a longitudinally expanding plasma. Simulations on
the Vienna Scientific Cluster with strong initial fields and physical masses will be
shown.
