    Notes: Abstract: We examine the behaviour of the concentration profiles of particles with repulsive interactions diffusing on a host lattice. At low temperature, the diffusion process is strongly influenced by the presence of ordered domains. We use mean field equations and Monte-Carlo simulations to describe the various effects which influence the kinetic behaviour. An effective diffusion coefficient is determined analytically and is compared with the simulations. Finite gradient effects on the ordered domains and on the diffusion are discussed. The kinetics studied is relevant for superionic conductors, for intercalation and also for the diffusion of particles adsorbed on a substrate.

    Notes: The phase transitions in the ground state of (1+1)-dimensional Ising models in a transverse field are studied for spin S=1/2, 1, 3/2, and 2 using the finite-size scaling method. The critical fields, thermal and correlation exponents are calculated as a function of S. The critical fields are monotonic functions of S but the exponents are S-independent and take their values for S=1/2. A novel calculational method based on universality of ratios of finite-size correlation length amplitudes is proposed and tested. It results in a much improved accuracy of extrapolation procedures. Such an universality appears to be a consequence of recently postulated conformal invariance of correlation functions of a class of two-dimensional classical models.

    Notes: The analysis of phase diagrams of one-dimensional quantum versions of axial next-nearest-neighbor Ising (ANNNI) and competing two- and four-spin interaction models in two dimensions was made. The zero-temperature wave-vector-dependent spectra for finite chains with up to L≤16 spins indicate a qualitative difference between the two models: while the existence of an incommensurate phase is confirmed for the ANNNI case, our results do not suggest that such a phase exists in the two- and four-spin model.

    Notes: A lattice model for heterogeneous catalysis on a flat metal surface (i.e., oxidation of carbon monoxide on platinum) has been investigated in mean field approximation and by Monte Carlo simulations. The cluster structure has been determined as a function of a single parameter YCO, directly related to the partial pressure of the carbon monoxide. At low YCO the surface is covered by a percolating oxygen cluster with small dispersed CO islands. As YCO is increased, the oxygen ceases to percolate. In parallel the CO clusters resp. the clusters of unoccupied sites increase in size and percolate just about when the system gets poisoned by the CO. The structure of the large clusters of all three types can be modeled by correlated percolation. The slowing down of the kinetics near the poisoning transition has been investigated and is shown to be related to the diffusion of clusters of unoccupied sites.
