Trapping and survival probability in two dimensions.
We investigate the survival probability Phi(n,c) of particles performing a random walk on a two-dimensional lattice that contains static traps, which are randomly distributed with a concentration c, as a function of the number of steps n. Phi(n,c) is analyzed in terms of a scaling ansatz, which allows us to locate quantitatively the crossover between the Rosenstock approximation (valid only at ...
متن کاملA crossing probability for critical percolation in two dimensions
Langlands et al. considered two crossing probabilities, π h and π hv , in their extensive numerical investigations of critical percolation in two dimensions. Cardy was able to find the exact form of π h by treating it as a correlation function of boundary operators in the Q → 1 limit of the Q state Potts model. We extend his results to find an analogous formula for π hv which compares very well...
متن کاملRandom Walk Studies in Two Dimensions
Computer studies of random walks in two dimensions are reported. The concept of degeneracy D is introduced in which only D steps are allowed at any one lattice point. Properties of the probability distribution function for the distance covered in N steps are discussed. The lifetime of a walk of degeneracy D is also examined. (Submitted to Journal of Mathematical Physics .) * -Work supported by ...
متن کاملFrequent Points for Random Walks in Two Dimensions
For a symmetric random walk in Z which does not necessarily have bounded jumps we study those points which are visited an unusually large number of times. We prove the analogue of the Erdős-Taylor conjecture and obtain the asymptotics for the number of visits to the most visited site. We also obtain the asymptotics for the number of points which are visited very frequently by time n. Among the ...
متن کاملRecurrence for persistent random walks in two dimensions
We discuss the question of recurrence for persistent, or Newtonian, random walks in Z2, i.e., random walks whose transition probabilities depend both on the walker’s position and incoming direction. We use results by Tóth and Schmidt–Conze to prove recurrence for a large class of such processes, including all “invertible” walks in elliptic random environments. Furthermore, rewriting our Newtoni...
