UV-filtered overlap fermions
Stephan Dürr, Christian Hoelbling, Urs Wenger
We discuss the kernel spectrum, locality properties and the axial-vector renormalization constant of UV-filtered overlap fermions. We find that UV-filtered overlap fermions have a…
Theoretical issues with staggered fermion simulations
Stephan Durr
The legality of the "rooting trick" in dynamical staggered fermion simulations is discussed, i.e. whether the theory with the Boltzmann weight yields th…
Dissociation of Feshbach Molecules into Different Partial Waves
Stephan Dürr, Thomas Volz, Niels Syassen +5
Ultracold molecules can be associated from ultracold atoms by ramping the magnetic field through a Feshbach resonance. A reverse ramp dissociates the molecules. Under suitable cond…
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…
Dissociation of ultracold molecules with Feshbach resonances
Stephan Dürr, Thomas Volz, Gerhard Rempe
Ultracold molecules are associated from an atomic Bose-Einstein condensate by ramping a magnetic field across a Feshbach resonance. The reverse ramp dissociates the molecules. The…
Characterization of elastic scattering near a Feshbach resonance in rubidium 87
Thomas Volz, Stephan Dürr, Sebastian Ernst +2
The s-wave scattering length for elastic collisions between 87Rb atoms in the state |f,m_f>=|1,1> is measured in the vicinity of a Feshbach resonance near 1007 G. Experimentally, t…
