Dirac Eigenmodes in an Environment of Dynamical Fermions
arXiv:hep-lat/0512045
Abstract
We discuss some properties of zero and near-zero modes of the Dirac operator, as observed in a recent simulation of 2-flavor QCD. The quarks have been implemented with the so-called Chirally Improved Dirac operator, which obeys the Ginsparg-Wilson relation to a good approximation. We present geometrical and statistical properties of these eigenmodes and eigenvalues.
