Chirality correlation within Dirac eigenvectors from domain wall fermions

In the dilute instanton gas model of the QCD vacuum, one expects a strong spatial correlation between chirality and the maxima of the Dirac eigenvectors with small eigenvalues. Following Horvath et al. we examine this question using lattice gauge theory within the quenched approximation. We extend the work of those authors by using weaker coupling, beta=6.0, larger lattices, 16(4), and an improved fermion formulation, domain wall fermions. In contrast with this earlier work, we find a striking correlation between the magnitudes of the chirality density, \psidagger(x) gamma(5) psi(x)\, and the normal density, psidagger(x) psi(x), for the low-lying Dirac eigenvectors.
