The impact of localized overlap eigenmodes on RMT measurements and topology
Anna Hasenfratz, Roland Hoffmann, Stefan Schaefer
The low energy eigenmodes of the continuum QCD Dirac operator are extended, but on the lattice, due to discretization effects, the Dirac operator can have localized eigenmodes. The…
Dynamical simulations with HYP-link Wilson fermions
Anna Hasenfratz, Roland Hoffmann, Stefan Schaefer
We present results from simulations of two dynamical flavors of improved Wilson fermions with nHYP smeared gauge links. We demonstrate that the simulation is stable at a pseudo-sca…
The chiral condensate on 2-flavor staggered configurations from an overlap operator
Anna Hasenfratz, Roland Hoffmann
We measure the low lying eigenmodes of an overlap Dirac operator on 2--flavor staggered configurations. By comparing the eigenmode distribution to the predictions of Random Matrix…
The rooted staggered determinant in the Schwinger model
Anna Hasenfratz, Roland Hoffmann
We investigate the continuum limit of the rooted staggered action in the 2-dimensional Schwinger model. We match both the unrooted and rooted staggered determinants with an overlap…
Restoring chiral symmetry to O(a^2) for dynamical Wilson fermions
Roland Hoffmann, Michele Della Morte, Francesco Knechtli +2
We present results for the non-perturbative determination of the improvement and renormalization factors of the isovector axial current for lattice QCD with two flavors of dynamica…
