Universality of subleading corrections for self-avoiding walks in presence of one-dimensional defects
نویسندگان
چکیده
We study three-dimensional self-avoiding walks in presence of a one-dimensional excluded region. We show the appearance of a universal sub-leading exponent which is independent of the particular shape and symmetries of the excluded region. A classical argument provides the estimate: ∆ = 2ν − 1 ≈ 0.175(1). The numerical simulation gives ∆ = 0.18(2).

Universality of subleading exponents induced by one dimensional defects: the case of self-avoiding walks
The presence of operators which are called irrelevant, in the terminology of the renormalization group approach, do not change the values of leading critical exponents. The determination of subleading exponents is generally a hard task. But there are systems, an example is studied in 1], which are simpler to study: in these cases one can nd observables for which an irrelevant operator contribut...
متن کاملOn anisotropic spiral self-avoiding walks
We report on a Monte Carlo study of so-called two-choice-spiral self-avoiding walks on the square lattice. These have the property that their geometric size (such as is measured by the radius of gyration) scales anisotropically, with exponent values that seem to defy rational fraction conjectures. This polymer model was previously understood to be in a universality class different to ordinary s...
متن کاملHigh-precision determination of the critical exponent γ for self-avoiding walks
We compute the exponent γ for self-avoiding walks in three dimensions. We get γ = 1.1575 ± 0.0006 in agreement with renormalization-group predictions. Earlier Monte Carlo and exact-enumeration determinations are now seen to be biased by corrections to scaling. The self-avoiding walk (SAW) is a well-known lattice model of a polymer molecule in a good solvent; moreover, because of its semplicity,...
متن کاملOn three-dimensional self-avoiding walk symmetry classes
In two dimensions the universality classes of self-avoiding walks (SAWs) on the square lattice, restricted by allowing only certain two-step configurations (TSCs) to occur within each walk, has been argued to be determined primarily by the symmetry of the set of allowed rules. In three dimensions early work tentatively found one (undirected) universality class different to that of unrestricted ...
متن کاملAddendum to ‘ On three - dimensional self - avoiding walk symmetry classes ’
In two dimensions the universality classes of self-avoiding walks on the square lattice, restricted by allowing only certain two-step configurations to occur within each walk, has been argued to be determined primarily by the symmetry of the set of allowed two-step configurations. In a recent paper, primarily tackling the three-dimensional analogues of these models, a novel two-dimensional mode...
