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…
Lattice calculation of the , and transition form factors and the hadronic light-by-light contribution to the muon
Antoine Gérardin, Willem E. A. Verplanke, Gen Wang +5
In this paper we present a first ab-initio calculation of the , and transition form factors performed with physical light-quark masses. We provide a comple…
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…
Dense and magnetized QCD from imaginary chemical potential
Szabolcs Borsányi, Bastian Brandt, Gergely EndrÅdi +4
In this work, we computed the equation of state of dense QCD in the presence of background magnetic fields using lattice QCD simulations at imaginary baryon chemical potential. Our…
