论文摘要
在细小的晶格间距下,晶格模拟会受到慢速(拓扑)模式的困扰,这些模式产生了较大的自相关时间。这些反过来导致难以估计的统计和系统错误。我们研究了4维SU(3)量规理论中的问题和可能的算法解决方案,特别关注激体顿更新和元动力学。
At fine lattice spacings, lattice simulations are plagued by slow (topological) modes that give rise to large autocorrelation times. These, in turn, lead to statistical and systematic errors that are difficult to estimate. We study the problem and possible algorithmic solutions in 4-dimensional SU(3) gauge theory, with special focus on instanton updates and Metadynamics.
