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…
Particle redistribution and slow decay of correlations in hard-core fluids on a half-driven ladder
Ronald Dickman, Ronaldo R. Vidigal
We study driven particle systems with excluded volume interactions on a two-lane ladder with periodic boundaries, using Monte Carlo simulation, cluster mean-field theory, and numer…
Asymptotic behavior of the order parameter in a stochastic sandpile
Ronaldo Vidigal, Ronald Dickman
We derive the first four terms in a series for the order paramater (the stationary activity density rho) in the supercritical regime of a one-dimensional stochastic sandpile; in th…
Series expansion for a stochastic sandpile
Jurgen F. Stilck, Ronald Dickman, Ronaldo R. Vidigal
Using operator algebra, we extend the series for the activity density in a one-dimensional stochastic sandpile with fixed particle density p, the first terms of which were obtained…
Path-integral representation for a stochastic sandpile
Ronald Dickman, Ronaldo Vidigal
We introduce an operator description for a stochastic sandpile model with a conserved particle density, and develop a path-integral representation for its evolution. The resulting…
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…
