The universal behavior of two-dimensional loop models can change dramatically when
loops are allowed to cross. We study models with crossings both analytically and with …

The structure of two-dimensional polymer chains in a solvent at different temperatures is still
far from being fully understood. Computer simulations of high-density macromolecular …

The structure of very thin polymer films formed by strongly adsorbed macromolecules was
studied by computer simulation. A coarse-grained model of strictly two-dimensional polymer …

The study of the effect of random impurities on the collapse of a flexible polymer in dilute
solution has had recent attention with consideration of semi-stiff interacting self-avoiding …

We study the interacting self-avoiding trail (ISAT) model on a Bethe lattice of general
coordination q and on a Husimi lattice built with squares and coordination q= 4. The exact …

Using extensive Monte Carlo simulations, we investigate the surface adsorption of self-
avoiding trails on the triangular lattice with two-and three-body on-site monomer-monomer …

A generalized model for interacting self-avoiding trails on a square lattice is presented and
studied using numerical transfer matrix methods. The model differentiates between on-site …

We investigate semi-stiff interacting self-avoiding walks on the square lattice with random
impurities. The walks are simulated using the flatPERM algorithm and the inhomogeneity is …

We study by computer simulation a recently introduced generalized model of self-interacting
self-avoiding trails on the square lattice that distinguishes two topologically different types of …

The complex zeros of the canonical (fixed walk-length) partition function are calculated for
both the self-avoiding trails model and the vertex-interacting self-avoiding walk model, both …
