One-loop for Wilson and Brillouin fermions with stout smearing or Wilson flow
Maximilian Ammer, Stephan Durr
We present results for the one-loop value of the improvement coefficient for Wilson and Brillouin fermions subject to stout smearing or Wilson flow, in combination…

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-…
