摘要:We investigate the distribution of low-lying eigenmodes of hermitianWilson-Dirac operator, HW,
with the gauge action whose form is designed to avoid topology change, as well as with the
standard plaquette action. On the quenched lattices, the former gauge action exhibits less density
of low-lying eigenmodes of HW compared to the latter at the same lattice spacing. We also show
preliminary results for the dynamical simulation with two avors of overlap fermions.
