Topology with Dynamical Overlap Fermions
Abstract
We perform dynamical QCD simulations with
n
f
=2
overlap fermions by hybrid Monte-Carlo method on
6
4
to
8

×16
lattices. We study the problem of topological sector changing. A new method is proposed which works without topological sector changes. We use this new method to determine the topological susceptibility at various quark masses.
