摘要

我们研究了在\(d=2\)维的非保守Ising模型中的粗化，其中远程相互作用衰减为\(\sim r^{-(d+\sigma )}\)，基于我们最近构思的非常有效的预决策方案，采用Metropolis蒙特卡罗计算机模拟。通过比较不同淬火温度之间的数值结果，我们证实了生长规律的温度独立性，并表明在粗化研究中合理选择温度可以获得较长的观测周期。

Temperature dependence of phase-ordering kinetics of the long-range Ising model with power-law decaying interactions

We study coarsening in the nonconserved Ising model in \(d=2\) dimensions with long-range interactions decaying as \(\sim r^{-(d+\sigma )}\), employing Metropolis Monte Carlo computer simulations based on our recently conceived very efficient predecision scheme. By comparing numerical results between different quench temperatures we confirm the temperature independence of growth laws and show that a sensible choice of temperature may yield longer observation periods in coarsening studies.
