Topological structure of the QCD vacuum probed via overlap fermions — •Yoshiaki Koma — DESY, 22603 Hamburg

Overlap fermions, which have exact chiral symmetry on the lattice, provide us with a powerful tool to investigate the topological structure of the QCD vacuum through lattice Monte Carlo simulations. We present our recent numerical results of such lattice simulations, especially, focusing on the localization properties of the topological charge density and of the Dirac eigenmodes. We then discuss a possible picture of the QCD vacuum.
