Query: Center Vortices and Chiral Symmetry Breaking in SU(2) Lattice Gauge
  Theory   We investigate the chiral properties of near-zero modes for thick classical
center vortices in SU (2) lattice gauge theory as examples of the phenomena
which may arise in a vortex vacuum. In particular we analyze the creation of
near-zero modes from would-be zero modes of various topological charge
contributions from center vortices. We show that classical colorful spherical
vortex and instanton ensembles have almost identical Dirac spectra and the
low-lying eigenmodes from spherical vortices show all characteristic properties
for chiral symmetry breaking. We further show that also vortex intersections
are able to give rise to a finite density of near-zero modes, leading to chiral
symmetry breaking via the Banks-Casher formula. We discuss the mechanism by
which center vortex fluxes contribute to chiral symmetry breaking.
