Granular flow trapped on an incline: dynamics of the sandpile.

Experimental results have been recently reported for the dynamics of two-dimensional sand fronts formed by the trapping of a flow running down an inclined plane. We explain the scaling law observed for the front profiles and give their analytic expression using a simple phenomonelogical model for interfacial shapes and interfacial flows of granular materials.

Random sequential adsorption of binary mixtures on a line.

A jamming coverage for the random sequential adsorption of binary mixtures of segments on the infinite line is derived. It always appears to be smaller than the coverage associated with the car parking problem. This has to be contrasted with dicrete models, where the coverage of the lattice by mixtures of segments of different sizes is more efficient than by single species.

Static A+B-->0 annihilation process in arbitrary dimension

The pair annihilation A+B-->0 of static particles distributed at random in a d-dimensional space is studied in the large time regime for a tunneling law. The consequences of a superposition approximation used to close the hierarchy of equations describing the process are analytically explored. It is shown that the density and pair correlations of surviving particles have scaling expressions which display the ordering and clustering effects.
