Title: | Zipping transition in a model of two crosslinked polymers | Authors: | LEONI, Peter VANDERZANDE, Carlo VANDEURZEN, Luc |
Issue Date: | 2001 | Publisher: | IOP PUBLISHING LTD | Source: | JOURNAL OF PHYSICS A-MATHEMATICAL AND GENERAL, 34(46). p. 9777-9791 | Abstract: | We study a model of two self-avoiding walks that are allowed to cross. An attractive energy is associated with each crossing. We present a number of exact results on the free energy of this model and show the existence of a zipping temperature, below which the number of crossings becomes macroscopic. We give heuristic arguments which show that in d = 2 and d = 3 this zipping transition occurs at infinite temperature. Exact enumeration and Monte Carlo simulations on the square lattice strongly support this conjecture and lead to a precise value for the crossover exponent. | Notes: | Limburgs Univ Ctr, Dept WNI, B-3590 Diepenbeek, Belgium.
