QCD Plasma Instabilities and Bottom-Up Thermalization

Evaluation of causal shear viscosity and relaxation time in QCD

where the first (second) equation represents energymomentum (the number) conservation, and dissipative effects such as viscosities are completely neglected (the above set of equations is exact, but for the ideal hydrodynamics all the higher expansion parameters, transport coefficients, in T μν and N are set to zero). Even though the ideal hydrodynamic simulations nicely coincides with experimen...

Plasma viscosity and cerebral blood flow.

We hypothesized that the response of cerebral blood flow (CBF) to changing viscosity would be dependent on "baseline" CBF, with a greater influence of viscosity during high-flow conditions. Plasma viscosity was adjusted to 1.0 or 3.0 cP in rats by exchange transfusion with red blood cells diluted in lactated Ringer solution or with dextran. Cortical CBF was measured by H(2) clearance. Two group...

Dynamics of Collective Decoherence and Thermalization

We analyze the dynamics of N interacting spins (quantum register) collectively coupled to a thermal environment. Each spin experiences the same environment interaction, consisting of an energy conserving and an energy exchange part. We find the decay rates of the reduced density matrix elements in the energy basis. We show that if the spins do not interact among each other, then the fastest dec...

Thermalization and plasma instabilities

I review recent analytical and numerical advances in the study of non-equilibrium quarkgluon plasma physics. I concentrate on studies of the dynamics of plasmas which are locally anisotropic in momentum space. In contrast to locally isotropic plasmas such anisotropic plasmas have a spectrum of soft unstable modes which are characterized by exponential growth of transverse (chromo)-magnetic fiel...
