Gw. Slater et Gi. Nixon, THE SIZE OF A POLYMER-CHAIN IN AN IMPERFECT ARRAY OF OBSTACLES - MONTE-CARLO RESULTS, The Journal of chemical physics, 108(8), 1998, pp. 3310-3312
Using Monte Carlo simulations, we test the prediction [Sommer and Blum
en, Phys. Rev. Lett. 79, 439 (1997)] that the radius-of-gyration of a
polymer chain moving in a periodic array of obstacles should be a mini
mum when a few defects are present. Our results agree qualitatively wi
th this prediction, but the excluded volume interactions greatly reduc
e the effect. (C) 1998 American Institute of Physics.
