Nonextensive diffusion as nonlinear response
James F. Lutsko, Jean Pierre Boon
The porous media equation has been proposed as a phenomenological ``non-extensive'' generalization of classical diffusion. Here, we show that a very similar equation can be derived…
Lattice gas automaton approach to "Turbulent Diffusion"
Jean Pierre Boon, Eric Vanden Eijnden, David Hanon
A periodic Kolmogorov type flow is implemented in a lattice gas automaton. For given aspect ratios of the automaton universe and within a range of Reynolds number values, the avera…
Dynamics of adsorbed islands with nanoscale resolution
N. Kruse, C. Voss, V. Medvedev +3
Surface catalytic processes produce, under certain conditions, small clusters of adsorbed atoms or groups, called {\em islands} which, after they have been formed, move as individu…
Propagation-Dispersion Equation
Jean Pierre Boon, Patrick Grosfils, James F. Lutsko
A {\em propagation-dispersion equation} is derived for the first passage distribution function of a particle moving on a substrate with time delays. The equation is obtained as the…
How fast does Langton's ant move?
Jean Pierre Boon
The automaton known as `Langton's ant' exhibits a dynamical transition from a disordered phase to an ordered phase where the particle dynamics (the ant) produces a regular periodic…
