Long Range Correlations in a Non Equilibrium System

A very remarkable property exhibited by non equilibrium systems is the appearance of coherence and long range order [1]. Once subjected to a constraint which maintains a system in a nonequilibrium steady state, fluctuations which occur in its different parts, are not independent. The correlation extends over the size of the sample [2–5]. We shall here study the origin of this behaviour in a simple example and describe a simulation set up in order to demonstrate this property.
