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…
Staggered fermions with taste splitting mass term on dynamical configurations
Gianluca Fuwa, Nuha Georgiev-Chreim, Christian Hoelbling
We present numerical results of staggered fermions with a taste splitting mass term on dynamical configurations. The rise of gluonic counterterms from rotational symmetry breaking…
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…
Symmetry properties of staggered fermions with taste splitting mass term
Nuha Chreim, Christian Hoelbling
We present analytical and numerical results on symmetry properties of staggered fermions with taste splitting mass terms. As staggered species split differently for different types…
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…
