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…
Topological susceptibility and excess kurtosis in SU(3) Yang-Mills theory
Stephan Durr, Gianluca Fuwa
We present a high-precision study of the topological susceptibility in pure gauge theory in four space-time dimensions. The result is based on ensembles at seven lattice sp…
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…
