论文摘要
相关长度$ξ$是玻璃动力学的关键数量,现在可以精确地用于实验和模拟中的自旋玻璃。但是,已知的分析方法导致大型外场或接近玻璃温度的差异。我们通过引入缩放定律来解决这个问题,该定律定律同时考虑了磁场和时间依赖性的旋转玻璃相关长度。根据Cumn单晶的实验测量和在Janus II专用计算机上的大规模模拟,对缩放定律成功进行了测试。
The correlation length $ξ$, a key quantity in glassy dynamics, can now be precisely measured for spin glasses both in experiments and in simulations. However, known analysis methods lead to discrepancies either for large external fields or close to the glass temperature. We solve this problem by introducing a scaling law that takes into account both the magnetic field and the time-dependent spin-glass correlation length. The scaling law is successfully tested against experimental measurements in a CuMn single crystal and against large-scale simulations on the Janus II dedicated computer.
