摘要：

We show that the fermion number density of low-lying eigenfunctions of the Dirac operator in quenched QCD peaks at the same locations that the density of chirality is peaked. We use an overlap Dirac operator that has an exact chiral symmetry. The gauge connections in the Dirac operator are smeared links. We consider two different smearing procedures. Our conclusion is independent of the smearing procedure used for the gauge links.
