MONTE-CARLO STUDY OF THE INTERACTING SELF-AVOIDING WALK MODEL IN 3 DIMENSIONS

We consider self-avoiding walks on the simple cubic lattice in which n eighboring pairs of vertices of the walk (not connected by an edge) ha ve an associated pair-wise additive energy. If the associated force is attractive, then the walk can collapse From a coil to a compact ball. We describe two Monte Carlo algorithms which we used to investigate t his collapse process, and the properties of the walk as a function of the energy or temperature. We report results about the thermodynamic a nd configurational properties of the walks and estimate the location o f the collapse transition.
