Abstract

We discuss the role of the microscopic stochastic dynamics in the macroscopic properties of a simple spin-Eip non-equilibrium mean field model where ferromagnetic and antiferromagnetic interactions are competing. We have found that different analytical forms for the dynamic mechanism give rise to diffeerent stationary states at low temperature, in contrast to what happens at equilibrium. We also 6nd an effective free-energy functional which allows us to classify the stable and metastable stationary solutions.
