摘要翻译:
最近鲍曼等人。[ARXIV:0709.3228V1]用Monte-Carlo模拟研究了具有均匀空间猝灭无序的二维Ising模型的相序动力学。他们发现,两次响应和相关函数与推广到z!=2的局部尺度不变性的预测是一致的。本文说明了为什么这是不正确的,并提出了一种可供选择的方法,该方法与数值结果更吻合。

英文摘要:
Recently Baumann et al. [arXiv:0709.3228v1] studied the phase-ordering kinetics of the two-dimensional Ising model with uniform spatially quenched disorder by Monte-Carlo simulations. They found that the two-time response and correlation functions are in agreement with the predictions of local scale invariance generalised to z!=2. The present paper shows why this is not true and suggests an alternative approach which leads to a much better agreement with the numerical results.
