Cutting the Energy Range in Multicanonical Monte Carlo Simulations — •Steffen Karalus^1,2, Wolfhard Janke¹, and Michael Bachmann² — ¹Institut für Theoretische Physik, Universität Leipzig, Germany — ²Soft Matter Systems Research Group, Institut für Festkörperforschung (IFF-2), Forschungszentrum Jülich, Germany

For a bead-and-spring polymer model, we investigate the dependence of several observables on the energy boundaries in a multicanonical Monte Carlo simulation. As expected, the results of the reweighting of statistical quantities to a certain temperature deviate seriously if a substantial part of the corresponding energy distribution lies outside the predefined energy range. However, structural quantities like the end-to-end distance are less affected than the energy itself.
