An equilibrium calculation of the thermal transport coefficients between two planes of arbitrary separation in a condensed phase

We present a method for the direct calculation at equilibrium of the shear viscosity and thermal conductivity over distances as short as one molecular diameter. The method is directly applicable to the calculation of viscosity and thermal conductivity in inhomogeneities such as the interface between coexisting phases. The method makes use of a novel extension of our recently developed boundary fluctuation theory.
