Decoupled Mode Theory of Critical Viscosity and Diffusion in the Binary-Liquid Phase Transition.
Abstract
The fluctuation-dissipation formula for the viscosity in terms of the stress tensor fluctuations reproduces the experimental logarithmic temperature dependence of the hydrodynamic viscosity. Using the theoretical wave number and frequency dependent viscosity in the problem of critical diffusion, the authors find that the effects of non-locality and retardation practically cancel, resulting in satisfactory agreement with a recent light scattering determination of the effective viscosity.
