Abstract
We observe two classes of nonequilibrium noise-induced transitions in two-dimensional nearest-neighbor coupled pendulums. One is characteriz ed by the drastic change of the shape of the stationary probability de nsity and the other by the symmetry-breaking order parameter. The corr esponding mechanisms are proposed. The nature of each transition is di scussed. The cooperative effect of the two phenomena is presented. The mean-field results are consistent with the ones from the numerical ca lculations.
