Hydrodynamic Boundary Conditions
Microscopic expressions for transport coefficients (such as viscosities or diffusion coefficients) of hydrodynamic equations in terms of equilibrium fluctuations have long been known. The choice of appropriate boundary conditions, however, has apparently been left to intuition. I will present a microscopic derivation of boundary conditions for the diffusion equation.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
