Journal ArticleDOI
Critical exponents of the classical three-dimensional Heisenberg model: A single-cluster Monte Carlo study
Christian Holm,Wolfhard Janke +1 more
TL;DR: The three-dimensional Heisenberg model is simulated on simple cubic lattices, using the single-cluster Monte Carlo update algorithm, and the expected pronounced reduction of critical slowing down at the phase transition is verified.
Journal ArticleDOI
Multicanonical Monte Carlo simulations
TL;DR: In this paper, the multicanonical reweighting method was used to overcome the problem of rare event states which lead to exponentially diverging autocorrelation times with increasing system size and hence to exponentially large statistical errors.
Journal ArticleDOI
Convergent strong-coupling expansions from divergent weak-coupling perturbation theory.
TL;DR: Divergent weak-coupling perturbation expansions for physical quantities can be converted into sequences of uniformly and exponentially fast converging approximations with the help of an additional variational parameter to be optimized order by order.
Journal ArticleDOI
Multicanonical chain-growth algorithm.
Michael Bachmann,Wolfhard Janke +1 more
TL;DR: A temperature-independent Monte Carlo method for the determination of the density of states of lattice proteins that combines the fast ground-state search strategy of the new pruned-enriched Rosenbluth chain-growth method and multicanonical reweighting for sampling the complete energy space is presented.
Journal ArticleDOI
Multicanonical study of coarse-grained off-lattice models for folding heteropolymers.
TL;DR: An optimization algorithm was applied to sequences with up to 55 monomers and the global-energy minimum found with lowest-energy states identified within the multicanonical simulation was compared to find out how reliable the multicansonical method samples the free-energy landscape, in particular for low temperatures.
