Similarity of fluctuations in correlated systems: The case of seismicity
摘要：
本文从自然时间的概念出发，讨论了平衡态临界现象和非平衡态系统中涨落的相似性。分析了世界范围内的地震活动以及圣安德列阿斯断层系统和日本的地震活动。选择一个序参量，并研究其相对于分布的标准差的波动。我们发现，标度分布落在同一条曲线上，有趣的是，这条曲线在四个数量级上表现出与几种平衡临界现象相似的特征（例如，2D伊辛模型）以及非平衡系统（例如，3D湍流）。
英文摘要：
We report a similarity of fluctuations in equilibrium critical phenomena and non-equilibrium systems, which is based on the concept of natural time. The world-wide seismicity as well as that of San Andreas fault system and Japan are analyzed. An order parameter is chosen and its fluctuations relative to the standard deviation of the distribution are studied. We find that the scaled distributions fall on the same curve, which interestingly exhibits, over four orders of magnitude, features similar to those in several equilibrium critical phenomena (e.g., 2D Ising model) as well as in non-equilibrium systems (e.g., 3D turbulent flow).
