Description
We study quark condensates using improved staggered fermions, where
zero modes of the Dirac operator give simple poles in the chiral
limit. We present a new method to identify the zero modes and
to subtract their contribution from the quark condensates.
Meanwhile we also identify the quantum numbers of
the zero modes in the staggered fermion formalism,
using the spectral flow method.
All the numerical results are calculated using
HYP-smeared staggered fermions on MILC asqtad lattices
and on MILC HISQ lattices.
