    • 22-24 have underscored the importance of the range of the attractive interactions in determining the stability of the fluid-fluid coexistence curve in a system of hard spheres and the importance of anisotropy in determining the phase diagrams of protein solutions.

    • note
    • Note that models different from ours but incorporating anisotropy of the chain backbone have been proposed for discrete polymer chains in the past (see refs. 25-29 for some examples). Our model, however, allows one to take the continuum limit without introducing further cutoffs in the theory.

    • note
    • 38,39 The renormalizability of such a field theory is well known, and it is guaranteed that, from a perturbative expansion, one can extract results that depend only on a finite number of parameters.

    • 1,1. That is, it is differentiable, and its derivative is a Lipschitz function (see ref. 46 and the references therein). An interesting problem, which we do not consider here, is the definition of a suitable measure in the continuum limit for such thick polymer centerlines. One possibility is, of course, to add, to the first term in eq 1, the three-body potential introduced in this work defined for all possible triplet radii, but this, for the reason just mentioned, does not lend itself to a straightforward perturbative formulation.

    • We call a tube space-filling if the smallest convex set that contains it (its convex hull) is simply connected (i.e., it has no holes in its interior).

    • Looking at the conformation with the chain not drawn, we can deserve that the balls are sitting on the sites of a regular lattice, possibly face-centered-cubic.
