Title: Localization properties of fermions and bosons

Abstract

The topological structure of the QCD vacuum can be probed by monitoring the spatial localization of the low-lying Dirac eigenmodes. This approach can be pursued on the lattice, and unlike the traditional one requires no smoothing of the gauge field. I review recent lattice studies, attempting to extract a consistent description. What emerges is a picture of the vacuum as a 'topological sandwich' of alternating, infinitely thin 3d layers of opposite topological charge.
