Domain growth morphology in curvature-driven two-dimensional coarsening

Abstract: We study the distribution of domain areas, areas enclosed by domain boundaries ͑"hulls"͒, and perimeters for curvature-driven two-dimensional coarsening, employing a combination of exact analysis and numerical studies, for various initial conditions. We show that the number of hulls per unit area, n h ͑A , t͒dA, with enclosed area in the interval ͑A , A + dA͒, is described, for a disordered initial condition, by the scaling function n h ͑A , t͒ =2c h / ͑A + h t͒ 2 , where c h =1/ 8 ͱ 3 Ϸ 0.023 is a universal c… Show more

“…When the system approaches the critical state, clusters of the new phase are formed by enhanced fluctuations and their size increases as does the correlation length. But this happens not instantly, because long range correlations develop gradually leading to the so-called dynamic phase transition (critical transition) (Bray 1994;Stanley 1999;Sicilia et al 2007;Varotsos et al 2011b, c). Thus, the time series emitted in such a nonequilibrium process will be nonstationary and p k , or the corresponding probability density function p(v) will no longer be independent of v.…”

“…364-365 of Varotsos et al 2011c). According to the dynamic scaling hypothesis (see Bray (1994); Sicilia et al (2007) and references therein), the time-dependent correlation length n at dynamic phase transitions scales as n µ t 1/z , where z is as mentioned above the so-called dynamic critical exponent. The time t is usually measured in Monte Carlo steps.…”

“…The pre-asymptotic dynamics leading to this regime have not been discussed in detail in the literature. It was noticed in [19] that the low-temperature evolution of a bidimensional 50:50 binary mixture after a quench from infinite temperature shares many points in common with the one generated by Glauber single spin-flip stochastic dynamics satisfying detailed balance [20,21]. On the one hand, an early approach to critical percolation was noticed, although the time needed to reach this state was not studied in detail.…”

“…A discussion of the scaling properties of the first term in terms of A/ 2 d (t), and the crossover of the scaling function from the regime in which the scaling variable varies from being much smaller to being much larger than one was presented in [19]. In the second regime the first term approaches the algebraic finite-size clusters distribution [19,21,36].…”

“…The situation is different when the system is not in equilibrium. When the system approaches the critical state, clusters of the new phase are formed by enhanced fluctuation and their size increases as does the correlation length (16)(17)(18). But this happens not instantly because long-range correlations develop gradually leading to the dynamic phase transition of the second order (17).…”
