Abstract
Spatial correlation functions in Lorentz gases maintained in nonequili brium steady states are studied. The correlation function of microscop ic number densities of the moving particle and scatterer is found to h ave long range spatial correlations that decay as 1/r(2) in three dime nsions in the presence of either a concentration gradient, a temperatu re gradient, or an electric held. Stronger correlations are found at h igher order in the electric held. Our analysis is based on a derived k inetic equation for the two-particle correlation function. Possible ex tensions of our work are discussed.
