Improving Inversions of the Overlap Operator
S. Krieg, N. Cundy, J. van den Eshof +3
We present relaxation and preconditioning techniques which accelerate the inversion of the overlap operator by a factor of four on small lattices, with larger gains as the lattice…

Numerical Methods for the QCD Overlap Operator:III. Nested Iterations
Nigel Cundy, Andreas Frommer, Jasper van den Eshof +3
The numerical and computational aspects of chiral fermions in lattice quantum chromodynamics are extremely demanding. In the overlap framework, the computation of the fermion propa…

Numerical Methods for the QCD Overlap Operator: II. Optimal Krylov Subspace Methods
G. Arnold, N. Cundy, J. van den Eshof +4
We investigate optimal choices for the (outer) iteration method to use when solving linear systems with Neuberger's overlap operator in QCD. Different formulations for this operato…
