介绍了自旋系统的事件链蒙特卡罗(ECMC)中出现的一种新的随机游走模型。在ECMC中,指定要更新的自旋的提升变量将其值更改为其交互的相邻自旋之一。这种运动可以看作是在有反馈的随机环境中的随机行走。我们在1维、2维和3维经典XY模型的情况下数值研究了这种随机游动,发现它在自旋系统的临界点附近是超扩散的。研究表明,ECMC的性能改善与这种反常行为有关。
We introduce a novel random walk model that emerges in the event-chain Monte Carlo (ECMC) of spin systems. In the ECMC, the lifting variable specifying the spin to be updated changes its value to one of its interacting neighbor spins. This movement can be regarded as a random walk in a random environment with a feedback. We investigate this random walk numerically in the case of the classical XY model in 1, 2, and 3 dimensions to find that it is superdiffusive near the critical point of the underlying spin system. It is suggested that the performance improvement of the ECMC is related to this anomalous behavior.
