Shear viscosity and entropy production related to viscous process in hot QGP at finite density
In the framework of irreversible thermodynamics, we studied the transport properties of QGP. Shear viscosity and non-equilibrium entropy density related to viscous process at finite density has been investigated in weakly coupled limit by using kinetic theory. The results show that the chemical potential increases viscosity yet decreases the non-equilibrium entropy density and thus contributes ...
متن کاملComputing the viscosity of the QGP on the lattice
Models treating the system produced in heavy ion collisions at RHIC as an ideal fluid have had significant success in describing the observed large elliptic flow.1), 2) Subsequently the leading corrections due to a finite shear viscosity η were estimated3) and led to a remarkably small upper bound on η. Recent relativistic viscous hydrodynamics simulations4)–6) have started to achieve a tighter...
متن کاملA non-local hydrodynamic model for the shear viscosity of confined fluids
We present a detailed analysis of a hydrodynamic constitutive model recently applied to study the non-local viscosity of highly confined inhomogeneous fluids (Zhang et al 2004 J. Chem. Phys. 121 10778, Zhang et al 2005 J. Chem. Phys. 122 219901). This model makes the assumption that, for pore widths significantly greater than the width of the viscosity kernel, one can approximate the true inhom...
متن کاملShear viscosity and shear thinning in two-dimensional Yukawa liquids.
A two-dimensional Yukawa liquid is studied using two different nonequilibrium molecular dynamics simulation methods. Shear viscosity values in the limit of small shear rates are reported for a wide range of Coulomb coupling parameter and screening lengths. At high shear rates it is demonstrated that this liquid exhibits shear thinning; i.e., the viscosity eta diminishes with increasing shear ra...
متن کاملShear Viscosity in the O(N) Model
We compute the shear viscosity in the O(N) model at first nontrivial order in the large N expansion. The calculation is organized using the 1/N expansion of the 2PI effective action (2PI-1/N expansion) to next-to-leading order, which leads to an integral equation summing ladder and bubble diagrams. We also consider the weakly coupled theory for arbitrary N , using the three-loop expansion of th...
