Systematic enumeration of configuration classes for entropic sampling of Ising models
Bruno Jeferson Lourenço, Ronald Dickman
We describe a systematic method for complete enumeration of configuration classes (CCs) of the spin-1/2 Ising model in the energy-magnetization plane. This technique is applied to…
Complete high-precision entropic sampling
Ronald Dickman, A. G. Cunha-Netto
Monte Carlo simulations using entropic sampling to estimate the number of configurations of a given energy are a valuable alternative to traditional methods. We introduce {\it tomo…
Contact process with sublattice symmetry breaking
Marcelo Martins de Oliveira, Ronald Dickman
We study a contact process with creation at first- and second-neighbor sites and inhibition at first neighbors, in the form of an annihilation rate that increases with the number o…
Glassy dynamics and hysteresis in a linear system of orientable hard rods
Jeferson J. Arenzon, Deepak Dhar, Ronald Dickman
We study the dynamics of a one-dimensional fluid of orientable hard rectangles with a non-coarse-grained microscopic mechanism of facilitation. The length occupied by a rectangle d…
An infinite-period phase transition versus nucleation in a stochastic model of collective oscillations
Vladimir R. V. Assis, Mauro Copelli, Ronald Dickman
A lattice model of three-state stochastic phase-coupled oscillators has been shown by Wood et al (2006 Phys. Rev. Lett. 96 145701) to exhibit a phase transition at a critical value…
Conserved directed percolation: exact quasistationary distribution of small systems and Monte Carlo simulations
Julio Cesar Mansur Filho, Ronald Dickman
We study symmetric sleepy random walkers, a model exhibiting an absorbing-state phase transition in the conserved directed percolation (CDP) universality class. Unlike most example…
Pair contact process with diffusion of pairs
F. L. Santos, Ronald Dickman, U. L. Fulco
The pair contact process (PCP) is a nonequilibrium stochastic model which, like the basic contact process (CP), exhibits a phase transition to an absorbing state. The two models be…
