Schwinger model simulations with dynamical overlap fermions

Presenter: Wolfgang Bietenholz — DESY Zeuthen

W. Bietenholz, S. Shcheredin and J. Volkholz

We present simulation results for the 2-flavour Schwinger model with dynamical overlap fermions. In particular we apply the overlap hypercube operator at seven light fermion masses. We collect sizable statistics in the topological sectors 0 and 1. From the eigenvalue densities we evaluate the chiral condensate Sigma based on Random Matrix Theory. For the very light fermion masses our results for Sigma are close to analytical low energy predictions in the continuum.
