Abstract:The interplay between the statistical properties of non-equilibrium systems systems with long-range interactions in equilibrium will be discussed. Driven systems tend to exhibit long-range correlations, resulting from the non detailed balance nature of their dynamics. Such correlations can sometimes be expressed by effective long-range interactions, even in cases where the dynamics is local. On the other hand studies of equilibrium systems with long-range interactions have demonstrated that they exhibit some unusual properties, such as inequivalence of statistical ensembles, negative specific heat and slow relaxation processes, with diverging characteristic time with the system size. Such features in driven systems with local dynamics will be demonstrated and some similarities between these two classes of systems will be discussed.
