  • Title: Test of the Stokes-Einstein relation in a two-dimensional Yukawa liquid.
    Author: Liu B, Goree J, Vaulina OS.
    Journal: Phys Rev Lett; 2006 Jan 13; 96(1):015005. PubMed ID: 16486470.
    Abstract:
    The Stokes-Einstein relation, relating the diffusion and viscosity coefficients D and eta, is tested in two dimensions. An equilibrium molecular-dynamics simulation was used with a Yukawa pair potential. Regimes are identified where motion is diffusive and D is meaningful. The Stokes-Einstein relation, Deta proportional k(B)T, was found to be violated near the disordering transition; under these conditions collective particle motion exhibits dynamical heterogeneity. At slightly higher temperatures, however, the Stokes-Einstein relation is valid. These results may be testable in strongly coupled dusty plasma experiments.
