摘要:

我们数值研究了Ising自旋玻璃中动力学非均匀性的老化特性。我们发现在老化过程中发生了一个相变。静态-动态对应意味着平衡状态下有限尺寸的系统具有服从有限尺寸标度的静态非均匀性,从而在热力学极限中发出类似的相变信号。我们计算的临界指数和过渡点的平衡设置,并使用它们来表明,老化的动态异质性可以描述的一个时间标度的时间尺度分析,与实验工作的潜在影响。

英文摘要:

We numerically study the aging properties of the dynamical heterogeneities in the Ising spin glass. We find that a phase transition takes place during the aging process. Statics-dynamics correspondence implies that systems of finite size in equilibrium have static heterogeneities that obey Finite-Size Scaling, thus signaling an analogous phase transition in the thermodynamical limit. We compute the critical exponents and the transition point in the equilibrium setting, and use them to show that aging in dynamic heterogeneities can be described by a Finite-Time Scaling Ansatz, with potential implications for experimental work.
