D. Bennettwood et al., LOW-TEMPERATURE 2D POLYMER PARTITION-FUNCTION SCALING - SERIES ANALYSIS RESULTS, Journal of physics. A, mathematical and general, 27(2), 1994, pp. 1-8
By utilizing newly extended series for self-avoiding walks and polygon
s with nearest-neighbour interactions on the square lattice we have ex
amined the validity of a recent conjecture on the scaling of their par
tition functions at low temperatures. The ratio of the walk to polygon
partition functions should have a length-dependent power law singular
ity, n(gamma D), at all temperatures. At low temperatures we find gamm
a(D) is 0.92+/-0.09 in distinction to the conjectured value of 19/16 =
1.1875, though we find agreement at high temperatures and at the thet
a-temperatures with the conjectured values there.
