We present a numerical study of the critical behavior of the nonequilibrium zero-temperature random field Ising model in two dimensions on a triangular lattice. Our findings, based on the scaling analysis and collapse of data collected in extensive simulations of systems with linear sizes up to L=65536, show that the model is in a different universality class than the same model on a quadratic lattice, which is relevant for a better understanding of model universality and the analysis of experimental data.
我们对二维三角晶格上的非平衡零温随机场伊辛模型的临界行为进行了数值研究。我们的研究结果基于对线性尺寸达(L = 65536)的系统进行广泛模拟所收集数据的标度分析和数据塌缩，结果表明该模型与二次晶格上的同一模型处于不同的普适类，这对于更好地理解模型普适性以及分析实验数据具有重要意义。
