How to Identify Zero Modes for Improved Staggered Fermions


  • Mr. Hwancheol JEONG

Primary authors



In the calculation of quark condensates using staggered fermions, the contribution induced by the zero modes of the Dirac operator behaves as a simple pole as approaching to the chiral limit. We use Lanczos algorithm to find the would-be zero modes of the staggered Dirac operator and identify their quantum numbers by the spectral flow method. We plan to apply this method to the calculation of quark condensates free of the zero modes.
