The dynamics are T=0 Glauber dynamicssupplemented by an injection mechanism, which is taken as a Poissonian flippingof one particular spin. We discuss the physical content of the results,specifically the influence of the rate of the Poisson process on the propertiesof the ldf. Commentaires: 18 pages, 8 figures. |
