Persistence in Random Walk in Composite Media
arXiv:0802.3598 · doi:10.1140/epjb/e2008-00300-1
Abstract
We consider a class of inhomogeneous media known as composite media that is often encountered in experimental sciences and investigate the persistence probability of a random walker in such a system. Analytical and numerical results for the crossover time scales has been obtained for a composite system with two homogeneous components and three homogeneous components respectively.
