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