Effective long-range interactions in driven systems with local dynamics
Driven systems with conserving dynamics tend to exhibit long-range correlations. Such correlations can sometimes be expressed by effective long range interaction, even in cases where the dynamics is local. On the other hand studies of systems with long-range interactions have demonstrated that they may exhibit some unusual properties, such as inequivalence of ensembles and slow relaxation processes, with diverging characteristic time with the system size. Such features in driven systems with local dynamics will be discussed.
