Aging and domain growth in the two--dimensional Ising spin glass model | | H. Rieger B.Steckemetz

26 Apr 1994 | | Journal: | Europhys.Lett. 27 (1994) 485 | | Abstract: | Interrupted aging in the two-dimensional Ising spin glass model with Gaussian couplings is established and investigated via extensive Monte-Carlo simulations. The spin autocorrelation function scales with $t/ au(t_w)$, where $t_w$ is the waiting time and $ au$ is equal to $t_w$ for waiting times smaller than the equilibration time $ au_{
m eq}$. The spatial correlations scale with $r/xi(t_w)$, where the correlation length $xi$ gives information about the averaged domain size in the system. Our results are better compatible with an algebraic growth law for $xi(t_w)$, although it can also nicely be fitted to $(log t_w)^{1/psi}$ with $psiapprox0.63$. | | Source: | arXiv, cond-mat/9404082 | | Services: | Forum | Review | PDF | Favorites | |
