Diffusion in stochastic sandpiles
S. D. da Cunha, Ronaldo R. Vidigal, L. R. da Silva +1
We study diffusion of particles in large-scale simulations of one-dimensional stochastic sandpiles, in both the restricted and unrestricted versions. The results indicate that the…
Wang-Landau sampling in three-dimensional polymers
A. G. Cunha Netto, C. J. Silva, A. A. Caparica +1
Monte Carlo simulations using Wang-Landau sampling are performed to study three-dimensional chains of homopolymers on a lattice. We confirm the accuracy of the method by calculatin…
Generic slow relaxation in a stochastic sandpile
Ronald Dickman
Simulations of a stochastic fixed-energy sandpile in one and two dimensions reveal slow relaxation of the order parameter, even far from the critical point. The decay of the activi…
Path Integrals and Perturbation Theory for Stochastic Processes
Ronald Dickman, Ronaldo Vidigal
We review and extend the formalism introduced by Peliti, that maps a Markov process to a path-integral representation. After developing the mapping, we apply it to some illustrativ…
N-Site approximations and CAM analysis for a stochastic sandpile
Ronald Dickman
I develop n-site cluster approximations for a stochastic sandpile in one dimension. A height restriction is imposed to limit the number of states: each site can harbor at most two…
