Query: Vacuum structure as seen by overlap fermions   Three complementary views on the QCD vacuum structure, all based on
eigenmodes of the overlap operator, are reported in their interrelation: (i)
spectral density, localization and chiral properties of the modes, (ii) the
possibility of filtering the field strength with the aim to detect selfdual and
antiselfdual domains and (iii) the various faces of the topological charge
density, with and without a cutoff \lambda_{\rm cut} = O(\Lambda_{QCD}). The
techniques are tested on quenched SU(3) configurations.
