论文摘要
我们通过平均场分析和数值模拟研究了一种使用无限范围相互作用的磁摩擦模型，并将其行为与我们先前考虑的短距离模型的行为进行了比较[H.〜Komatsu，phys。当温度高于临界值$ t_c $时，这种无限范围的模型总是遵守Stokes Law，而当温度低于$ T_C $时，它显示了从Dieterich-Ruina法律到Stokes Law的交叉或过渡。考虑到我们先前研究中的短距离模型表明，无论温度高于平衡过渡温度还是低于平衡的过渡温度，高温状态的行为是这两个模型之间的主要区别。
We investigate a model of magnetic friction with the infinite-range interaction by mean field analysis and a numerical simulation, and compare its behavior with that of the short-range model that we considered previously [H.~Komatsu, Phys.\ Rev.\ E.\ \textbf{100}, 052130 (2019)]. This infinite-range model always obeys the Stokes law when the temperature is higher than the critical value, $T_c$, whereas it shows a crossover or transition from the Dieterich--Ruina law to the Stokes law when the temperature is lower than $T_c$. Considering that the short-range model in our previous study shows a crossover or transition irrespective of whether the temperature is above or below the equilibrium transition temperature, the behavior in the high-temperature state is the major difference between these two models.
