We calculate the connective constant for self-avoiding walks on the simple cubic lattice to unprecedented accuracy, using a novel application of the pivot algorithm. We estimate that μ = 4.684 039 931 ± 0.000 000 027. Our method also provides accurate estimates of the number of self-avoiding walks, even for walks with millions of steps. 

Count ing sel f -avoiding walks on the hexagonal lat t ice

In how many ways can you go for a walk along a lattice grid in such a way that you never meet your own trail? In this snapshot, we describe some combinatorial and statistical aspects of these

Endless self-avoiding walks

We introduce a self-avoiding walk model for which end-effects are completely eliminated. We enumerate the number of these walks for various lattices in dimensions two and three, and use these

Three-dimensional terminally attached self-avoiding walks and bridges

We study terminally attached self-avoiding walks (SAWs) and bridges on the simple cubic lattice, both by series analysis and Monte Carlo methods. We provide strong numerical evidence supporting a

Supermultiplicative relations in models of interacting self-avoiding walks and polygons

Fekete’s lemma shows the existence of limits in subadditive sequences. This lemma, and generalisations of it, also have been used to prove the existence of thermodynamic limits in statistical

High-precision estimate of the hydrodynamic radius for self-avoiding walks.

A method of analysis which eliminates the leading correction to scaling results in a highly accurate estimate for the Flory exponent, and improved estimates for other universal properties that measure the chain dimension.

The Lee–Yang theory of adsorbing self-avoiding walks is presented. It is shown that Lee–Yang zeros of the generating function of this model asymptotically accumulate uniformly on a circle in the

New scaling laws for self-avoiding walks: bridges and worms

We show how the theory of the critical behaviour of d-dimensional polymer networks gives a scaling relation for self-avoiding bridges that relates the critical exponent for bridges to that of

The Lee-Yang theory of adsorbing self-avoiding walks is presented. It is shown that Lee-Yang zeros of the generating function of this model asymptotically accumulate uniformly on a circle in the

Growing self avoiding walk trees

The Growing self avoiding walk model (GSAW) was proposed to explain statistical mechanics of the growth process in polymerization. Close examination of the model reveals that it is suited only for

Critical scaling of lattice polymers confined to a box without endpoint restriction

We study self-avoiding walks on the square lattice restricted to a square box of side L weighted by a length fugacity without restriction of their end points. This is a natural model of a confined

Accurate estimate of the critical exponent nu for self-avoiding walks via a fast implementation of the pivot algorithm.

A fast implementation of the pivot algorithm for self-avoiding walks is introduced, which is used to obtain large samples of walks on the cubic lattice of up to 33x10{6} steps, and the critical exponent nu is determined to great accuracy.

A prototypical problem on which techniques for exact enumeration are tested and compared is the enumeration of self-avoiding walks. Here, we show an advance in the methodology of enumeration, making

The pivot algorithm for self-avoiding walks has been implemented in a manner which is dramatically faster than previous implementations, enabling extremely long walks to be efficiently simulated, and promises to be widely useful.

Scaling of the atmosphere of self-avoiding walks

The number of free sites next to the end of a self-avoiding walk is known as the atmosphere of the walk. The average atmosphere can be related to the number of configurations. Here we study the

The pivot algorithm: A highly efficient Monte Carlo method for the self-avoiding walk

This paper finds that the pivot algorithm is extraordinarily efficient: one “effectively independent” sample can be produced in a computer time of orderN, and presents a rigorous proof of ergodicity and numerical results on self-avoiding walks in two and three dimensions.

Canonical Monte Carlo determination of the connective constant of self-avoiding walks

We define a statistic an(w), the size of the atmosphere of a self-avoiding walk, w, of length n, with the property that an(w) → μ as n → ∞, where μ is the growth constant of lattice self-avoiding
