Parallelization of Computational Physics Algorithmsng model and a cluster identification algorithm which is used for percolation or percolation-like problems. The algorithm for the identification of clusters for the percolation-like problems was tested on the Swendsen-Wang method for the simulation of the Ising model. Simulation results are presente

Classification and Exponents of Cellular Automataolfram-type criteria. Only about one out of ten rules leads to a fixed point or an oscillation of period two. More useful seems the classification according to damage spreading: seven percent of the rules let an initial disturbance die out, in 30 percent the damage remains localized, and in the othe

New Interfacial Phenomena in a Driven Diffusive Systemaper we describe the behavior of a driven lattice gas when we impose shifted periodic boundary conditions, which are used in equilibrium to generate tilted interfaces. In the case of small shifts, our study shows a non-analyticity in the internal energy, in agreement with previous results which indi

Spin Dynamics of Cuprate Superconductors: Exact Results from Numerical Continued Fraction Expansionswith up to 16 spins, obtained by numerical continued fraction expansion techniques. Our results are compared to a recently proposed Schwinger boson mean-field theory. We find that the mean-field theory represents an excellent approximation to the exact spin excitation spectra and to the static struc

Structural Anisotropy of Aggregation Clustersed DLCA, RLCA and DLA clusters, we calculate a set of multipole expansion terms, to quantitatively evaluate the cluster anisotropy. Through examination of the scaling of these multipole terms, we show that the anisotropy of cluster-cluster aggregates is scale-invariant, while for DLA clusters of les
