Stout smearing and Wilson flow in lattice perturbation theory
Maximilian Ammer, Stephan Durr
We present the expansion of stout smearing and the Wilson flow in lattice perturbation theory to order , which is suitable for one-loop calculations. As the Wilson flow is g…

Eigenvalue based taste breaking of staggered, Karsten-Wilczek and Borici-Creutz fermions with stout smearing in the Schwinger model
Maximilian Ammer, Stephan Durr
In two spacetime dimensions staggered fermions are minimally doubled, like Karsten-Wilczek and Borici-Creutz fermions. A continuum eigenvalue is thus represented by a pair of near-…

Calculation of at one-loop order for Brillouin fermions
Maximilian Ammer, Stephan Durr
The Brillouin action is a Wilson-like lattice fermion action with a 81-point stencil, which was found to ameliorate the Wilson action in many respects. The Sheikholeslami-Wohlert c…
