Parallel tempered metadynamics: Overcoming potential barriers without surfing or tunneling
Parallel tempered metadynamics: Overcoming potential barriers without surfing or tunneling
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 autocorrelation times. This can lead to simulation runs that are effectively stuck in one topological sector, a problem known as topological …
