Non-perturbative improvement of nHYP smeared Wilson fermions
Roland Hoffmann, Anna Hasenfratz, Stefan Schaefer
Using Schroedinger functional techniques, we determine the coefficient of the clover term necessary for non-perturbative O(a) improvement of hypercubic smeared Wilson fermions on a…

Localized eigenmodes of the overlap operator and their impact on the eigenvalue distribution
Anna Hasenfratz, Roland Hoffmann, Stefan Schaefer
In a system where chiral symmetry is spontaneously broken, the low energy eigenmodes of the continuum Dirac operator are extended. On the lattice, due to discretization effects, th…
