Extraction of shear viscosity in stationary states of relativistic particle systems
relativistic particle systems stationary states Extraction of shear viscosity

2011/7/21
Starting from a classical picture of shear viscosity we construct a stationary velocity gradient in a microscopic parton cascade. Employing the Navier-Stokes ansatz we extract the shear viscosity coef...
