摘要:

重叠费米子在晶格上具有精确的手征对称性,因此是研究QCD真空的手征和拓扑结构的合适工具。我们研究了猝灭规范场组态的各种手征和拓扑性质。这包括本征模的局部化和手征性质,紫外线过滤的场强张量的局部结构,以及拓扑电荷波动的结构。我们得出结论,真空具有多重分形结构。

英文摘要:

Overlap fermions have an exact chiral symmetry on the lattice and are thus an appropriate tool for investigating the chiral and topological structure of the QCD vacuum. We study various chiral and topological aspects of quenched gauge field configurations. This includes the localization and chiral properties of the eigenmodes, the local structure of the ultraviolet filtered field strength tensor, as well as the structure of topological charge fluctuations. We conclude that the vacuum has a multifractal structure.
