Universality of collapsing two-dimensional self-avoiding trails
D P Foster
Results of a numerically exact transfer matrix calculation for the model of Interacting Self-Avoiding Trails are presented. The results lead to the conclusion that, at the collapse…
Extended Defects in the Potts-Percolation Model of a Solid: Renormalization Group and Monte Carlo Analysis
H. T. Diep, Miron Kaufman
We extend the model of a 2 solid to include a line of defects. Neighboring atoms on the defect line are connected by ?springs? of different strength and different cohesive energ…
Random walks pertaining to a class of deterministic weighted graphs
Thierry Huillet
In this note, we try to analyze and clarify the intriguing interplay between some counting problems related to specific thermalized weighted graphs and random walks consistent with…
Bethe approximation for a DNA-like self-avoiding walk model with variable solvent quality
D P Foster, C Pinettes
The phase diagram and critical behaviour of a simple toy model for DNA zipping/unzipping is examined in the framework of the Bethe approximation. The effects of solvent quality are…
