论文摘要

我们在自旋玻璃的非平衡动力学中发现了动态效应，该动力学与平衡温度混乱相似。我们将这种效果称为动态温度混乱，在很大程度上是空间异质的。钥匙控制量是随时间生长的旋转玻璃连贯长度。我们对动态温度混乱的详细表征为分析最近和即将进行的实验的分析铺平了道路。由于在Janus〜I II定制超级计算机上进行的非平衡动力学迄今为止的最大模拟，这项工作已成为可能。

We find a dynamic effect in the non-equilibrium dynamics of a spin glass that closely parallels equilibrium temperature chaos. This effect, that we name dynamic temperature chaos, is spatially heterogeneous to a large degree. The key controlling quantity is the time-growing spin-glass coherence length. Our detailed characterization of dynamic temperature chaos paves the way for the analysis of recent and forthcoming experiments. This work has been made possible thanks to the most massive simulation to date of non-equilibrium dynamics, carried out on the Janus~II custom-built supercomputer.
