CRITICAL-BEHAVIOR AT THE THETA-POINT OF SELF-AVOIDING WALKS ON A MANHATTAN LATTICE

Abstract:
The authors study the collapse of self-attracting self-avoiding walks on a Manhattan lattice, by means of phenomenological renormalization group techniques. Their results support a recent prediction of nonuniversality for the entropic exponent gamma . The surface exponents are in the same universality class as the theta transition on undirected lattices, thus differing from those of the theta ' point. They use a two-parameter renormalization group to obtain estimates of the crossover exponent.
