    • note
    • c(∞). Indeed, while simulations of critical phenomena with E=∞ [3] are consistent with the coarse-grained field-theoretic results with a finite field, some debate remains [5,6]. Our resolution is simple: we restrict ourselves to finite fields.

    • Larger fields, above around 2 in our units, suppress the triangular anisotropy in both lattice and coarse-grained approaches [R. K. P. Zia (private communication)]. However, if the anisotropy is not strictly zero, questions about its sign remain.

    • note
    • By eye, rotating the field π/4 with respect to the lattice axes induces an anisotropy reversal.

    • note
    • We do not cover the entire phase space of deterministic coarse-grained models. In general, one requires a fully anisotropic surface tension, which can be selected by higher-order gradients in Eq. (2). One also can require a fully anisotropic particle mobility, rather than the simple elliptical anisotropy of Eq. (5), with more general order-parameter dependence as well.
