Binary fluids in Vycor: Anticorrelated random fields.

Binary fluids in Vycor are a realization of anticorrelated random-field systems. The change from uncorrelated to anticorrelated fields has a profound effect at zero temperature. At any finite temperatures an effective uncorrelated random field of entropic origin is generated and thus the large scale behavior is that of uncorrelated systems. The possible crossovers from the pure-system behavior to the eventual uncorrelated behavior and from an effective anticorrelated to uncorrelated behavior are discussed.
