Numerical simulations of anisotropic plasmas show specific instability behaviors.

Real-time lattice results confirm theoretical predictions for stationary and expanding plasmas.

The work enhances understanding of plasma dynamics in non-equilibrium conditions.

Abstract

The generalization of the hard thermal loop effective theory to anisotropic plasmas is described with a detailed discussion of anisotropic dispersion laws and plasma instabilities. The numerical results obtained in real-time lattice simulations of the hard loop effective theory are reviewed, both for the stationary anisotropic case and for a quark-gluon plasma undergoing boost-invariant expansion.
