Scaling tests with dynamical overlap and rooted staggered fermions
Stephan Dürr, Christian Hoelbling
We present a scaling analysis in the 1-flavor Schwinger model with the full overlap and the rooted staggered determinant. In the latter case the chiral and continuum limit of the s…
Feshbach Spectroscopy of a Shape Resonance
Thomas Volz, Stephan Dürr, Niels Syassen +3
We present a new spectroscopy technique for studying cold-collision properties. The technique is based on the association and dissociation of ultracold molecules using a magnetical…
A comparative study of overlap and staggered fermions in QCD
S. Dürr, Ch. Hoelbling, U. Wenger
We perform a comparative study of the infrared properties of overlap and staggered fermions in QCD. We observe that the infrared spectrum of the APE/HYP improved staggered Dirac op…
Gauge action improvement and smearing
Stephan Dürr
The effect of repeatedly smearing SU(3) gauge configurations is investigated. Six gauge actions (Wilson, Symanzik, Iwasaki, DBW2, Beinlich-Karsch-Laermann, Langfeld; combined with…
A comparative study of overlap and staggered fermions in the Schwinger model
Stephan Dürr, Christian Hoelbling
We investigate the validity of the square rooting procedure of the staggered determinant in the context of the Schwinger model. We find some evidence that at fixed physical quark m…
Staggered eigenvalue mimicry
Stephan Dürr, Christian Hoelbling, Urs Wenger
We study the infrared part of the spectrum for UV-filtered staggered Dirac operators and compare them to the overlap counterpart. With sufficient filtering and at small enough latt…
