SU中滤波方法的比较（3）格点规范理论
Comparison of filtering methods in SU(3) lattice gauge theory
摘要：
我们系统地比较过滤方法用于提取拓扑激发格点规范配置。我们发现，有一个很强的相关性的拓扑电荷密度得到APE和斯托特涂抹。此外，淬火和动力学配置的第一个定量分析揭示了它们的拓扑结构的一个重要差异：拓扑电荷密度更分散，当动力学夸克存在。这一事实也意味着，必须非常小心地处理涂抹，不要破坏这些特征结构。
英文摘要：
We systematically compare filtering methods used to extract topological excitations from lattice gauge configurations. We show that there is a strong correlation of the topological charge densities obtained by APE and Stout smearing. Furthermore, a first quantitative analysis of quenched and dynamical configurations reveals a crucial difference of their topological structure: the topological charge density is more fragmented, when dynamical quarks are present. This fact also implies that smearing has to be handled with great care, not to destroy these characteristic structures.
