Quantum Zero-Point Critical Fluctuations in Arrays of Ultrasmall Josephson Junctions). Specifically, we mention results: (i) close to the renormalized semi-classical critical temperature and its successful comparison to experiment, (ii) The existing renormalization-group, self-consistent harmonic approximation and QMC evidence for a low temperature quantum induced phase transition

Quantum Critical Exponents of a Planar Antiferromagnetent development of cluster algorithms for quantum spin systems, the loop algorithms. Our results support the conjecture that the quantum Heisenberg antiferromagnet is in the same universality class as the O(3) nonlinear sigma model. The Berry phase in the Heisenbrg antiferromagnet do not seem to be

Fragmentation Scaling of the Percolation Clusterace renormalization group method on two and three dimensions. We obtain the accurate values of critical exponents λ and ? describing the scaling of fragmentaion rate and the distribution of cluster masses produced by a binary fragmentation. Our results for λ and ? in two dimensions agree with the pr

Magnons in Heisenberg Chains with Random ±J Nearest-Neighbor Interactionssummarized. A combination of numerical and analytical techniques are utilized to obtain the limiting behavior at low energies. The magnon contribution to the low temperature specific heat is calculated and compared with the specific heat of a spin-1/2 chain with similar interactions that was calcula

Eight-State Potts Model on the Quasiperiodic Octagonal Tiling: Free Boundary Effectsing are investigated using the importance-sampling Monte Carlo method and the single histogram technique. The analysis of the probability distributions of the internal energy evidences that such numerical data suffer from drastic free boundary effects. However, the size dependence of the free energy
