First experiences with HMC for dynamical overlap fermions
Achim Bode, Urs M. Heller, Robert G. Edwards +1
We describe an HMC algorithm for dynamical overlap fermions which makes use of their good chiral properties. We test the algorithm in the Schwinger model. Topological sectors are r…
Topology and Chiral Symmetry in QCD with Overlap Fermions
Robert G. Edwards, Urs M. Heller, Joe Kiskis +1
We briefly review the overlap formalism for chiral gauge theories, the overlap Dirac operator for massless fermions and its connection to domain wall fermions. We describe properti…
Reducing Discretization Errors in Lattice QCD Spectroscopy
Sara Collins, R. G. Edwards, U. M. Heller +1
The improved Wilson quark action - the clover action - is constructed to have smaller discretization errors than the normal Wilson quark action. We test this in a quenched spectros…
On the Dynamics of Light Wilson Quarks
A. D. Kennedy, R. G. Edwards
We describe recent results obtained as part of the High Energy Monte Carlo Grand Challenge (HEMCGC) project concerning the behaviour of lattice QCD with light dynamical Wilson quar…
