The statistical mechanics of polymers with excluded volume

Edwards, S F·1965·Proceedings of the Physical Society

Abstract

The probability distribution of the configurations of a polymer consisting of freely hinged links of length l and excluded volume v is studied. It is shown that the interaction of the polymer with itself can be represented by considering the polymer under the influence of a self-consistent field which reduces the problem to an equation like the Hartree equation for an atom. This can be solved asymptotically, giving the probability of the n th link of the polymer passing through the point r to be ( L )exp[-27{ r -(5/3) 3/5 ( v /3π l ) 1/5 L 3/5 } 2 (1/20 Ll )] where L = nl is the length along the polymer and ( L ) the normalization. Thus the mean square of r , r 2 , is (5/3) 6/5 ( v /3π l ) 2/5 L 6/5 . The theory is extended to polymers of finite length, to the excluded random walk problem and to n dimensions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
