论文摘要
3D Edwards-Anderson自旋玻璃的热量磁化数据是使用等待时间方法作为模拟工具生成的，并使用记录动力学解释。我们验证了连续旋转的簇被震颤，与记录大小的能量波动相关的非平衡事件的推翻，并表明震颤是一个对数杆子的过程，即，在最初的淬灭中计算的泊松过程，其平均值取决于系统年龄的平均值。我们的结果与实验热量磁化发现以及E-A模型的自发波动动力学相比有利。 倾覆簇的大小的对数增长与类似的实验结果以及自旋自旋空间相关函数的长度尺度的增长有关。该分析支持等待时间方法作为模拟工具和记录动力学作为衰老动力学的粗粒方法的适用性。
Thermoremanent magnetization data for the 3D Edwards-Anderson spin glass are generated using the Waiting Time Method as simulational tool and interpreted using Record Dynamics. We verify that clusters of contiguous spins are overturned by quakes, non-equilibrium events linked to record sized energy fluctuations and show that quaking is a log-Poisson process, i.e. a Poisson process whose average depends on the logarithm of the system age, counted from the initial quench. Our results compare favorably with experimental thermoremanent magnetization findings and with the spontaneous fluctuation dynamics of the E-A model. The logarithm growth of the size of overturned clusters is related to similar experimental results and to the growing length scale of the spin-spin spatial correlation function. The analysis buttresses the applicability of the Waiting Time Method as a simulational tool and of Record Dynamics as coarse-graining method for aging dynamics.
