| + | **Predrag 2012-02-15** Read [[http://arxiv.org/abs/1202.2904|An analytic approximation to the Diffusion Coefficient for the periodic Lorentz Gas]] by Angstmann and Morriss. The say: "An approximate stochastic model for the topological dynamics of the periodic triangular Lorentz gas is constructed. The model, together with an extremum principle, is used to find a closed form approximation to the diffusion coefficient as a function of the lattice spacing. This approximation is superior to the popular Machta and Zwanzig result and agrees well with a range of numerical estimates." | ||
