Parallel Tempered Metadynamics for full QCD
Timo Eichhorn, Gianluca Fuwa, Christian Hoelbling +1
We present an algorithm that addresses topological freezing in lattice QCD simulations by combining parallel tempering with collective-variable-based enhanced sampling methods, and…
Enhanced Sampling Techniques for Lattice Gauge Theory
Timo Eichhorn, Gianluca Fuwa, Christian Hoelbling +1
In theories with topological sectors, such as lattice QCD and four-dimensional SU(N) gauge theories with periodic boundary conditions, conventional update algorithms suffer from to…
Parallel Tempered Metadynamics
Timo Eichhorn, Gianluca Fuwa, Christian Hoelbling +1
When approaching the continuum limit in lattice QCD or other theories in a setup with topological sectors, conventional update algorithms experience a particularly severe form of c…
Parallel Tempered Metadynamics: Overcoming potential barriers without surfing or tunneling
Timo Eichhorn, Gianluca Fuwa, Christian Hoelbling +1
At fine lattice spacings, Markov chain Monte Carlo simulations of QCD and other gauge theories with or without fermions are plagued by slow modes that give rise to large autocorrel…
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…
Comparison of topology changing update algorithms
Timo Eichhorn, Christian Hoelbling
In modern lattice simulations, conventional update algorithms do not allow for tunneling between topological sectors at fine lattice spacings. We compare the viability of multiple…
