Metadynamics Surfing on Topology Barriers in the Schwinger Model
Christian Hoelbling, Timo Eichhorn, Philip Rouenhoff +1
Topological freezing is a well known problem in lattice simulations: with shrinking lattice spacing a transition between topological sectors becomes increasingly improbable, leadin…
Topology changing update algorithms for SU(3) gauge theory
Timo Eichhorn, Christian Hoelbling, Philip Rouenhoff +1
At fine lattice spacings, lattice simulations are plagued by slow (topological) modes that give rise to large autocorrelation times. These, in turn, lead to statistical and systema…
Locality of staggered overlap operators
Nuha Chreim, Christian Hoelbling, Christian Zielinski
We give an explicit proof for the locality of staggered overlap operators. The proof covers the original two flavor construction by Adams as well as a single flavor version. As in…
QED and strong isospin corrections in the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon
L. Parato, Sz. Borsanyi, Z. Fodor +11
Recently, the Budapest-Marseille-Wuppertal collaboration achieved sub-percent precision in the evaluation of the lowest-order hadronic vacuum polarization contribution to the muon…
