Plasma Instabilities in an Anisotropically Expanding Geometry
Abstract
We study (3+1)D kinetic (BoltzmannVlasov) equations for relativistic plasma particles in a one dimensionally expanding geometry motivated by ultrarelativistic heavyion collisions. We set up local equations in terms of YangMills potentials and auxiliary fields that allow simulations of hard (expanding) loop dynamics on a lattice. We determine numerically the evolution of plasma instabilities in the linear (Abelian) regime and also derive their latetime behavior analytically, which is consistent with recent numerical results on the evolution of the socalled melting colorglass condensate. We also find a significant delay in the onset of growth of plasma instabilities which are triggered by small rapidity fluctuations, even when the initial state is highly anisotropic.

NonAbelian plasma instabilities play a crucial role in the nonequilibrium dynamics of a weakly coupled quarkgluon plasma, and they importantly modify the standard perturbative bottomup thermalization scenario in heavyion collisions. Using the auxiliaryfield formulation of the hardloop effective theory, we study numerically the realtime evolution of instabilities in an anisotropic collisionless YangMills plasma undergoing longitudinal freestreaming expansion. In this first realtime lattice simulation we consider the most unstable modes, longwavelength coherent color fields that are constant in transverse directions and which therefore are effectively 1+1 dimensional in spacetime, except for the auxiliary fields which also depend on discretized momentum rapiditymore »

Collective modes and instabilities in anisotropically expanding ultarelativistic plasmas
The time evolution of collective modes in an expanding ultrarelativistic and (effectively) Abelian plasma is studied in the hardloop approximation semianalytically by means of integrodifferential equations. A previous treatment is generalized to arbitrary orientation of wave vectors with respect to the direction of anisotropy and thus to a fully 3+1 dimensional situation. Moreover, initial fluctuations are allowed in both gauge fields and currents, which is necessary in the case of (stable) longitudinal modes. For unstable (Weibel) modes, this generalization of initial conditions reduces drastically the lower bound on the delay in the onset of growth that was found previously bymore » 
Bulk viscosity of anisotropically expanding hot QCD plasma
The bulk viscosity, {zeta} and its ratio with the shear viscosity, {zeta}/{eta} have been studied in an anisotropically expanding pure glue plasma in the presence of turbulent color fields. It has been shown that the anisotropy in the momentum distribution function of gluons, which has been determined from a linearized transport equation eventually leads to the bulk viscosity. For the isotropic (equilibrium) state, a recently proposed quasiparticle model of pure SU(3) lattice QCD equation of state has been employed where the interactions are encoded in the effective fugacity. It has been argued that the interactions present in the equation ofmore » 
Stability of the anisotropically inflating Bianchi type VI expanding solutions
A special class of the Bianchi type VI expanding solutions was speculated to break the cosmic nohair theorem that will not approach the latetime de Sitter solution. We will show that an unstable mode always exists when the perturbation of the field equations is applied to the system. In addition to a modelindependent perturbation formula, a simplification is also achieved by the introduction of a {delta}R=0 solution good for quadratic models in all Bianchi spaces. The result shows that this special class of anisotropically expanding solutions is unstable.
