Probability of dimer reassociation in two dimensions
We study the problem of dimer dissociation and reassociation in two dimensions through a random-walk-like calculation. In order to find the probability of dimer reassociation after a given number of hops, we give the exact analytical solution for the probability of a first return into a given region (rhombus) for a two-dimensional random walker on a squared lattice.
