摘要：We investigate the correlation between the topological charge density and the small eigenvectors
of the overlap Dirac operator on ensembles generated at four different quark masses using
dynamical overlap fermions. We identify topological structures in the QCD vacuum, and by investigating
their size, shape and topological charge, we determine that the small eigenvalues of the
Dirac operator are dominated by approximately hyper-spherical objects with integer topological
charge.
