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…
