Abstract
We consider a system of N horizontal lines where colliding vertical sticks are placed initially according to an equilibrium prescription; they move parallel to the lines and collide; the collisions take place between sticks of the same line and of the adjacent ones. The asymptotic behavior of a tagged stick is diffusive, and the self-diffusion constant is inversely proportional to N.File in questo prodotto:
