Abstract

We measured persistence exponents θ(φ) of Ostwald ripening in two dimensions, as a function of the area fraction φ occupied by coarsening domains. The values of θ(φ) in two systems, succinonitrile and brine, quenched to their liquid-solid coexistence region, compare well with one another, providing compelling evidence for the universality of the one-parameter family of exponents. For small φ, θ (φ) □ 0.39 φ, as predicted by a model that assumes no correlations between evolving domains. These constitute the first measurements of persistence exponents in the case of phase transitions with a conserved order parameter.
