    • We assume that the singular terms in the LGW expansion discussed in Refs. are negligible in the 2D intermediate-energy regime of the layered system under consideration. (The singularities are not present in the asymptotic 3D AFM regime.) As the singularities are interaction-generated, microscopic details become relevant here. E.g., close to nesting, AF criticality will result already from small interactions, such that the non-LGW regime is expected to be pushed to very small energy scales.

    • The standard Hertz model does not describe the ordered phase of a metallic magnet because it does not account for the modified order-parameter dynamics due to gaps in the fermionic spectrum. However, at least for the antiferromagnet in d>2, precursor effects of these gaps (" pseudogaps") have been shown to be irrelevant for the critical dynamics, see
