Title: | Nonequilibrium wetting transition in a nonthermal 2D Ising model | Authors: | HOOYBERGHS, Jef Indekeu, J. O. |
Issue Date: | 2011 | Publisher: | SPRINGER | Source: | EUROPEAN PHYSICAL JOURNAL B, 81(2). p. 155-163 | Abstract: | Nonequilibrium wetting transitions are observed in Monte Carlo simulations of a kinetic spin system in the absence of a detailed balance condition with respect to an energy functional. A nonthermal model is proposed starting from a two-dimensional Ising spin lattice at zero temperature with two boundaries subject to opposing surface fields. Local spin excitations are only allowed by absorbing an energy quantum (photon) below a cutoff energy E (c) . Local spin relaxation takes place by emitting a photon which leaves the lattice. Using Monte Carlo simulation nonequilibrium critical wetting transitions are observed as well as nonequilibrium first-order wetting phenomena, respectively in the absence or presence of absorbing states of the spin system. The transitions are identified from the behavior of the probability distribution of a suitably chosen order parameter that was proven useful for studying wetting in the (thermal) Ising model. | Notes: | [Hooyberghs, J.] VITO, Flemish Inst Technol Res, B-2400 Mol, Belgium.
