Topological Susceptibility and Zero Mode Size in Lattice QCD
Robert G. Edwards, Urs M. Heller, Rajamani Narayanan
Abstract
We use the overlap formalism to define a topological index on the lattice. We study the spectral flow of the hermitian Wilson-Dirac operator and identify zero crossings with topological objects. We determine the topological susceptibility and zero mode size distribution, and we comment on the stability of our results.
