Decorrelation of the topological charge in tempered Hybrid Monte Carlo simulations of QCD

Please always quote using this URN: urn:nbn:de:0297-zib-4168

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.
