| 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. |
