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...
The Wigner-Fokker-Planck equation: Stationary states and large-time behavior
Wigner-Fokker-Planck equation Stationary states large-time behavior
2010/11/11
We consider the linear Wigner-Fokker-Planck equation subject to confining potentials which are smooth perturbations of the harmonic oscillator potential. For a certain class of perturbations we prove ...
One Parameter Scaling Theory for Stationary States of Disordered Nonlinear Systems
Parameter Scaling Stationary States of Disordered Nonlinear Systems
2010/4/6
We show, using detailed numerical analysis and theoretical arguments, that the normalized participation number of the stationary solutions of disordered nonlinear lattices obeys a one-parameter scalin...
Stationary states and fractional dynamics in systems with long range interactions
Stationary states fractional dynamics long range interactions
2010/4/7
Dynamics of many-body Hamiltonian systems with long range interactions is studied, in the context of the so called $\alpha-$HMF model. Building on the analogy with the related mean field model, we con...
