We analyse the scaling behaviour of the partition function and the statistics of nearest-neighbour contacts, as well as the average geometric size of the walks, and compare our results to $1/d$-expansions and to excellent rigorous bounds that exist. In particular, we obtain precise values for the connective constants, $\\mu_5=8.838544(3)$, $\\mu_6=10.878094(4)$, $\\mu_7=12.902817(3)$, $\\mu_8=14.919257(2)$ and give a revised estimate of $\\mu_4=6.774043(5)$. All of these are by at least one order of magnitude more accurate than those previously given (from other approaches in $d>4$ and all approaches in $d=4$). Our results are consistent with most theoretical predictions, though in $d=5$ we find clear evidence of anomalous $N^{-1/2}$-corrections for the scaling of the geometric size of the walks, which we understand as a non-analytic correction to scaling of the general form $N^{(4-d)/2}$ (not present in pure Gaussian random walks).", "revisions": [ { "version": "v1", "updated": "2001-04-09T02:15:42.000Z" } ], "analyses": { "keywords": [ "self-avoiding walks", "high dimensions", "pure gaussian random walks", "high-precision monte-carlo simulations", "general form" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
