One-dimensional asymmetric simple exclusion process with open boundarys is considered. This is a kind of lattice gas model. Particles enter the system at left edge, diffuse asymmetrically in the bulk and leave out of the sysytem at right edge. They are also subject to the hard-core exclusion interaction. It has been known that the steady state properties of the model depends crutially on the boundary conditions. This boundary induced phase transition is explained from the point of view of the orthogonal polynomials.

    The recently developed dynamic percolation theory is used to solve the problem of diffusion of interacting particles in lattice-gas models within an effective medium approximation. The approach is based on the observation that the motion of a tracer particle in a system of (similar or different)...

    If an ensemble of particles moving parallel to the x axis in the positive direction impinges on a piecewise continuous potential confined to the interval [-a,a] (a>0) it will divide into a transmitted ensemble and a reflected ensemble. It is shown that the classical results for the means,...

    The quantum free particle on the sphere Sκ2 (κ > 0) and on the hyperbolic plane Hκ2 (κ < 0) is studied using a formalism that considers the curvature κ as a parameter. The first part is mainly concerned with the analysis of some geometric formalisms appropriate for the description...
