Solving Sign Problems with Meron Algorithmsdentify clusters that help match configurations of equal weight but opposite signs and hence do not contribute to the path integral. Avoiding these clusters, called merons, alleviates the sign problem and in certain cases solves it completely. Among the variety of problems that can be solved using t

Low-Temperature Thermodynamics of Quantum Systemss of the system are calculated from a single Lanczos run. The method may be extended systematically to all temperatures. We apply the method to a Heisenberg model for the two-dimensional quantum disordered antiferromagnet CaV.O..

The Dynamical Cluster Approximation: A New Technique for Simulations of Strongly Correlated Electrontores nonlocal correlations to the dynamical mean field approximation (DMFA). The DCA is in the thermodynamic limit and becomes exact for an infinite cluster size, while reducing to the DMFA for a cluster size of unity. Using the one-dimensional Hubbard Model as a nontrivial test of the method, we s

An ,-Fold Algorithm for the Heisenberg Model: An Equilibrium Studyc for the classical Heisenberg model. Our algorithm reproduces both the static and the dynamics at equilibrium, obtained from a traditional Metropolis algorithm, but requires orders of magnitude less computer time at low temperatures. The treatment is general, and can be extended to other continuous
