SC 99-28 Ernst-Michael Ilgenfritz, Werner Kerler, Hinnerk Stüben: Decorrelation of the topological charge in tempered Hybrid
Monte Carlo simulations of QCD
Abstract: We study the improvement of simulations of QCD with
dynamical Wilson fermions by combining the Hybrid Monte
Carlo algorithm
with parallel tempering. As an indicator for
decorrelation we use the topological charge.
