A pr 1 99 4 Aging and domain growth in the two – dimensional Ising spin glass model

چکیده
Interrupted aging in the two-dimensional Ising spin glass model with Gaus-sian couplings is established and investigated via extensive Monte-Carlo simulations. The spin autocorrelation function scales with t/τ (t w), where t w is the waiting time and τ is equal to t w for waiting times smaller than the equilibration time τ eq. The spatial correlations scale with r/ξ(t w), where the correlation length ξ gives information about the averaged domain size in the system. Our results are better compatible with an algebraic growth law for ξ(t w), although it can also nicely be fitted to (log t w) 1/ψ with ψ ≈ 0.63.

Non-equilibrium dynamics in the random bond Ising chain: A reminiscence of aging in spin glasses
Results of extensive Monte-Carlo simulations that investigate the out-ofequilibrium dynamics of the one-dimensional Ising spin glass model with a Gaussian bond-distribution are presented. At low enough temperatures a typical (interrupted) aging scenario is established as in twoand similar to three-dimensional spin glass models. Since the underlying mechanism is a slow domain-growth we study in ...
متن کاملMagnetic Properties in a Spin-1 Random Transverse Ising Model on Square Lattice
In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
متن کاملNumerical Study on Aging Dynamics in the 3d Ising Spin-glass Model — Quasi-equilibrium Behaviour of Spin Auto-correlation Functions
Using Monte Carlo simulations, we have studied aging phenomena in three-dimensional Gaussian Ising spin-glass model focusing on quasi-equilibrium behavior of the spin autocorrelation functions. Weak violation of the time translational invariance in the quasiequilibrium regime is analyzed in terms of effective stiffness for droplet excitations in the presence of domain walls. The simulated resul...
متن کاملDynamical aspects of equilibrium and off - equilibrium simulations of a three - dimensional Heisenberg spin glass
Spin-glass and chiral-glass orderings of a three-dimensional isotropic Heisenberg spin glass are studied both by equilibrium and off-equilibrium Monte Carlo simulations with emphasis on their dynamical aspects. The model is found to exhibit a finite-temperature chiral-glass transition without the conventional spin-glass order. Although chirality is an Ising-like quantity from symmetry, universa...
متن کاملNumerical Study of Aging Phenomena in Short-Ranged Spin Glasses
Aging phenomena of short-range Ising spin glass models have been investigated using Monte Carlo simulations. It is found that in the low-temperature spin-glass phase the mean domain size exhibits a crossover from a power-law growth associated with the critical fluctuation at the transition temperature to slower growth inherent in the low-temperature phase. The temperature dependence of the grow...
