摘要：We present measurements of the chiral condensate and topological charge history for 2+1 flavour
Domain Wall QCD, and compute spectral flows for the corresponding Hermitian Wilson Dirac
operator. We considered several lattice spacings, with the DBW2 and Iwasaki gauge actions and
different sea quark masses on a volume of 163×32 and a fifth dimension of size 8. These results
show the spectral structure on 2+1 flavours of DWF QCD. We also discuss the dependence of
the tunneling rate on lattice spacing and gauge action. All data was generated on the QCDOC
machines.
