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.
